Tom Clancys Genius Essays - Tom Clancy, Novel Series,

Tom Clancy's genius English Tom Clancy's genius The Cold War and post Cold War eras have brought with them many interesting aspects. New technologies initially meant for mass destruction filter down into the civilian world, making current lives easier. One example of this is the anti-lock braking systems of today's cars. Originally designed to slow fighter-planes on landing without skidding, these systems make it safer for parents to take their children on vacation. One less noted advancement the eras brought is a considerable amount of exciting and forewarning fiction. While most authors chose to warn of nuclear and post nuclear holocaust, one significant author chose a different approach. Tom Clancy chose to write of conventional warfare and sometimes unconventional enemies. Between his novel Red Storm Rising and Debt of Honor, Tom Clancy makes evident the changing face of America's enemies and threats, while staying true to issues that keep people interested in his books. Published in 1986, Red Storm Rising is Tom Clancy's second novel dealing with the former Soviet Union as a potential enemy. This was a time when America's finest tank and infantry units went on exercises in Germany fully armed with the expectation that the Russians could attack them at any time. This was also a time when the Soviets did the same exercises with the same amount of live ammunition. Therefore there was reason enough to worry about potential conflicts. Deep within the ocean waters, submarines played similar cat and mouse games with other submarines and surface ships. However some of these submarines were more dangerous then a whole army because they were fully loaded with nuclear missles. These facts were well know to the American public and made Red Storm Rising all the more real when it combined land and ocean warfare in a way that captivated millions of readers. The book begins as the Soviet Union's ability to provide their own oil is cut off by a terrorist attack. Right away it is noted that two very frightening events have just happened. Terrorism, for one, is a major scare tactic that can and does strike fear into millions. This was demonstrated by two suspected attacks in the U.S. recently (Bombing of Flight 800 and the Olympic Park bombing). Secondly, the threat of losing petroleum resources is enough to drive governments to drastic measures. This fact is evident in the world's participation in the 1991 Gulf War. The leaders of the Soviet Union decided that the only way to prevent the total collapse of their economy and country was to seize the oil rich Middle East. They also realized that the countries that make up the North Atlantic Treaty Organization (NATO), in particular the United States would not stand for this hostile action. Consequently the Soviets determine that it will be necessary to neutralize NATO conventionally; that is to say without nuclear weapons. Of course, throughout the Cold War the many themes of the U.S.S.R. attacking the U.S are presented by various authors. All of these had the same result: nuclear holocaust. One exception is that Red Storm Rising is the first to present it (theme of U.S.S.R. attacking the U.S.) in a non-nuclear scenario. This is very intriguing to examine the possibilities which include all the new technological weapons in the American and Soviet arsenals. Red Storm Rising captivates audiences with its techno-wizardry of smart bombs and satellite guided cruise missles. ?It was like an arcade game. Big, slow-moving blips denoted the aircraft. Smaller, quicker blips were the Mach-2 missiles (Clancy 178).? This was seen by a radar operator who was under attack during Red Storm Rising. However it is not the high tech gadgets that appeal to audiences of Red Storm Rising. There is a personable feel as the reader becomes better acquainted with the characters and sympathizes for them and the decisions they make. This is not the story of machines run by artificial intelligence, these are real people, friends, and neighbors of the reader. Bob Toland was a middle-level analyst at the National Security Agency. He'd left the Navy after six years whey the adventure of uniformed service had palled, but he remained an active reservist. His work at NSA dovetailed nicely with his naval reserve service.

Servant Leader Formation Paper Essay Example | Topics and Well Written Essays - 1500 words

Servant Leader Formation Paper - Essay Example The spirit of leadership rises from the leader letting others achieve and improve their capabilities and goals. Servant leadership starts as a feeling before it develops into a leadership attribute (Blanchard, 2001, Pg 352). A servant leader seeks to serve rather than control. Needless to say that their primary goals are more inclined towards human life enhancement. The focus on the less privileged in the society moves the role of a servant leader form an organization but to the society as a whole. Certain imperative characteristics that define and distinguish a servant leader are as stated below. These need to be necessarily communicated to the current and the future servant leaders of the organization to mould future servant leaders. Inculcating and allowing each of the group members to learn the attributes listed below goes a long way in becoming a servant leader. Empathy - The first quality for any strong leader is to stay empathetic. By empathy we mean the ability of a leader to put him, in the shoes of others, to act, react and understand the emotions and actions of his peers or his subordinates. A servant leader works to understand and empathize with others. The ability of a leader to accept people as they are and not reject them as people, though their performance or actions may not be fully accepted is an important attribute to make them a servant leader. Listening - Communication has always been an important attribute for a leader. This is even so true for a servant leader. The ability of a servant leader to inculcate patience and listen to issues and problems of peer and others within the organization plays a vital role in defining his or her success. Servant leaders naturally identify and try to resolve the problems of the group. Their ability to listen to what is being said and not said allows them to stay in touch with the inner self of their peer and assist them in guiding and reacting to their group's problems. Foresight - Foresight is an important characteristic of a servant leader. Servant leaders not only learn from lessons of their past but also from others. Their ability to foresee and link the future to the present allows them to take decisions that have a positive impact on the group and the organization. Their ability to foresee is a consequence of both experience and intuitive mind set. Commitment to group - One of the remarkable characteristics of servant leaders is their ability to look through people beyond their contribution at work or in social life. Being strongly committed to the cause of the group and helping the group work towards achieving it allows the servant leader to reach the personal, professional life of their group. This commitment to a large extent defines an individual as a servant leader. Compromise between individual comfort and group comfort - A servant leader serves the group. In many situations, the chances are that the thoughts of the group may be entirely different from that of the servant leader. Having said so, the servant leader needs to necessarily develop the attitude to compromise on his or her personal comfort or the ultimate goal or benefit of the group. Making dream to reality - An analysis of the servant le

Is it moally acceptable for government agencies (NSA, CIA FBI) to Essay

Is it moally acceptable for government agencies (NSA, CIA FBI) to eavesdrop on domestic phone calls or intercept emails of its c - Essay Example For this exercise to be acceptable by all bodies involved, the bodies conducting the eavesdropping had to obtain a warranty from the United States Foreign Surveillance Court. This could have legalized the whole exercise and no questions could have arisen from the different bodies that raised their concerns (Risen 19). Many laws against this act have been formulated. These include the wireless telegraphy act 2006 and the regulation of investigatory powers act 2000. Although this act of intercepting emails is good for the security of the country, the bodies conducting the interception should look, for a warranty, to do the same. The N.S.A, F.B.I together with C.I.A, argue that taking of warranties will alert the potential terrorists and the search would not be effective. This essay outlines the reasons why use of unwarranted emails eavesdropping is not good (Bamford 145). First is the fact that this is a breach of civil liberty. Individuals are supposed to be covered under civil rights , which gives them freedom to do what is legally right to the extent that they do not interfere with other people’s life (Radden 19). The act of eavesdropping on emails and phone calls is a violation of human rights to expression, interaction, and speech. These laws cover individuals enabling them to interact and communicate freely without others getting concerned about other individuals’ conversation. In addition to this, confrontation of individuals to know whom they were communicating with is a violation of human rights. The security department needs to show proof of a warranty to eavesdrop someone’s emails and a warranty authorizing interviews in regard to the messages intercepted (Radden 64). The act of eavesdropping is a violation of the privacy policy of the company providing the communication (Janczewski and Colarik 128). Companies providing communication services always have privacy policies by which they are supposed to abide. They are supposed to ensu re that no third party individual encounters the contents of the message unless warranted officially by the government. It is the right of an individual to sue any company that allows third party individuals to get the contents of his emails without an official warranty (Radden 59). The act of eavesdropping can as well cause safety issues to the contents of the message. Certain email messages and calls are supposed to be private and confidential. Such emails explaining or having monetary discussions can easily be decrypted, and the information be used in a bad way so that the money is diverted (Bamford 125). This is very possible within the security bodies; N.S.A, F.B.I and C.I.A simply because the agencies have employees of varied nature. Individuals who can use such advantage to divert the monetary value of the emails and calls to his account exist. This can be very disappointing to the individual and all the people associated with the transaction. The fact that the interception o f the emails is not warranted would make individuals have the privilege of going around the issue without fear from court orders and imprisonment (Janczewski and Colarik 91). It can also be difficult to know the exact person that conducted the transfer of the monetary contents from the email. This is because individuals with the capability to intercept emails may have much more technology to hide any traceable information as to where the money went. This is thus a big problem to the company

Geology Essay Example | Topics and Well Written Essays - 250 words - 4

Geology - Essay Example This then resulted to the formation of the sun and planets that make up the solar system (Seeds 80). This has been supported by the ratio of the aluminum isotopes found in the meteorites that were formed when the molecular cloud collapsed. The scientists came up with a model that explains the unusual levels that the isotope contained (Seeds 79). They stated that the levels could have been because the isotopes were being fed in the molecular cloud at the time the supernova event was occurring. The seismic waves caused by the supernova event were hot in nature thus when they collided with the cold molecular cloud of gas resulted to it colliding. This consequently led to the formation of the solar system. As it is seen the death of the star that was caused by the seismic waves that were a result of the supernova event made way for the solar system to be formed. This helps us to understand the fact that the solar system came into existence as a result of the death of a star (Seeds

Approaches to Financial Crisis Management

Approaches to Financial Crisis Management LITERATURE REVIEW The following Literature review starts with past studies and researches based on the crisis in general. Different types of crisis are referred and what kind of effects do they cause to businesses and people. Additionally are past studies on management strategies in period of recession and what does a business has to follow, not only old businesses but also new. Furthermore we focus on the new start up businesses that decide to grow in period of crisis. What Past studies and researches found and proved through history, when again in the past there was a recession. Crisis A crisis is an adverse incident with an unpredictable outcome (Campbell, 1999; Coombs, 1999; Coombs Holladay, 2002; Ruff Aziz, 2003). Interestingly, it should be pointed out that there is a wide range of crisis categories, from a basic ‘internal versus external’ introduced by Evans and Elphick (2005, p. 135), to a more complex system proposed by Henderson (2007) who categorized crises into economic crisis; political crisis; socio-cultural crisis; environmental crisis; technological crisis; and commercial crisis. Although there are numerous approaches to crisis categorization, The Pacific Asia Travel  Association (2003) has suggested that crises can be largely categorized into two major types, which are human-made and natural-made crises. It is crucial for one to understand that not all types of crisis lead to the same consequences, differing from one another in terms of the scope and extent of damage caused (Aktas Gunlu, 2005). Different public reactions to both human-made and natural crises provide a clear example of the critical differences in the public’s reaction to different types of crisis. The public normally reacts more negatively to the effects of human-made crises than to those of a natural crisis. While it is generally conceded that organizations have little control over natural crises, human-made crises can devastate the established reputation of an organization. As human-made crises are usually preventable, this type of crisis therefore often receives severe public condemnation (Pearson Mitroff, 1993). Furthermore, different crisis types, particularly both natural and human induced crises, are neither absolutely predictable nor avoidable. This means while crises occur rarely and randomly, it is also true that no industries are unaffected by those crises. In  response to the near certainty of experiencing crises, it is suggested that organizations come up with a plan for minimizing the damage of, and accelerating the recovering from, such crises through the development of crisis management strategies (Faulkner, 2001). Therefore the concept of crisis management is discussed below. Crisis Management Being able to effectively respond to a crisis is critical for the survival of an organization. Whether an organization is prepared or not for a possible crisis usually depends on senior officials and other private operating within organizations. More importantly, studies have shown that organizations with an established crisis management approach are able to effectively communicate and respond in the event of a crisis (King III, 2002). Clearly, it is crucial for an organization to have a crisis management approach in place. In general, a crisis management approach can be viewed simply as involving the  Ã¢â‚¬Ëœ4 Rs’ of a four-stage process, which are reduction, readiness, response and recovery (Evans   Elphick, 2005). The Pacific Asia Travel Association (2003) has summarized and described each stage as follows: Reduction. In this phase, an organization’s analysis of strengths, weakness, opportunities, and threats (a SWOT analysis) will help the managers to assess a potential crisis and to prepare a contingency plan. After identifying potential crises, organizations need to be prepared by developing strategic, tactical and communication plans. Readiness, the second phase, crisis response and crisis simulation exercises are very important in order to acquire and maintain crisis management skills as managers and staff need to be ready for the impact and stress from crises. Response, the third phase, a contingency plan is implemented immediately after a crisis occurs, as organizations that have a well-established crisis management plan tend to be more successful in handling crises. A crisis communication strategy should be utilized to communicate with not only the customer, but also the stakeholders and the public. Recovery. In the last phase, the crisis recovery could be measured by the speed with which an organization resumes full business operations; the degree to which a business recovers to pre-crisis levels, or the amount of crisis-resistance added since the crisis occurred. Whilst corporate managers are faced with the reality of trying to implement this process (Evans Elphick, 2005), it should be noted that all stages of the crisis management process need to be flexible, which allows for potential evaluation and modification, depending on the nature of the crisis/disaster (its magnitude, scale and time pressure) and stakeholder response to strategies. Although crisis management is a requirement for organizations, and although business leaders recognize this, many do not undertake productive steps to address crisis situations. Managers who do take productive steps however will be in a much better position to respond when a crisis or disaster affects an organization or destination (Ritchie, 2004). So, because a start up business in time of a recession has knowledge of all the stages, it is easier to handle the crisis as they are aware of the consequences a bad economy has on a business. Measurement are been taken before they have any bad influence on the ir business from the recession. Start-ups business and existing business in time of recession First of all, we are going to study past studies that were done during a period of recession and see how they coped during the period. Small businesses in their starting period are responsible for the New England turnaround and the Massachusetts miracle in the early 1980s. Small businesses had the willingness to expand and form and were the reason the economy became so strong (Lamp, 1988). It was found by Birch (1987) that the keys to new job creation are pioneering firms. Stable economies that can offer a proper environment for start-ups and existing firms to expand and grow but on the other hand those that cannnot offer such an environment usually suffer. With the reason that large businesses are reengineering, resizing and most importantly, downsizing, many people are leaning towards small business as a reason of economic expansion. In 1994 Dun Bradstreet anticipated that 3.1 million new jobs would be created with 72.4 percent following up from new firms with less than 100 employ ees. New small firms with less than 20 employees have also been seen as the creators of new markets for large firms and as the nations job creators (Phillips, 1993). As from this example, it is clear that new businesses and especially a small one can survive and also take advantage of the recession, if handled in the right way. Small businesses are considered to add to the local economy and therefore invigorate the economy (Violaris, Harmandas and Loizidis, 2012). When there is an economic recession, it is a period where all firms are struggling for their survival, especially for new firms and start-ups the failing rate proved to be higher compare to larger companies (Latham, 2009 p180-201, Lawless and warren,2005). However, some scholars have argued that smaller firms (start-ups) can have their own unique competitive advantage since they are closer to the market and realize the customers’ needs more easily (Young and Shepherd, 2005, Tavakoli and McKierman, 2009) There are several success factors that new companies can adopt in order to survive the crisis or event to expand in this recessionary environment. According to professor, John Quelch (2012), a success factor during a recession is that the firms should continue spending on marketing and in order to survive a firm should be able to realize how the needs and preferences of customers change in order to adopt their strategies. They should keep 8 factors in mind when making the marketing plans: research the customer, focus on family values, maintain marketing spending, adjust product portfolios, support distributors, adjust pricing tactics, stress market share and emphasize core values. A research of (Srinivasam, 2009) on six recessions that took place in US, from 1969 to 2007, showed that increases in RD (research and development) decreases profits for B2B and B2C, while there is no change for service firms. However, more expenditure in advertising increases the profits to B2B and B2C but not for firms that are in service. Also another research agreed that increases in advertising spending increases returns during recession but disagrees that increases on RD decreases returns (Graham and Frankenberger, 2008). Another strategy for start ups to follow during recessionary environment is a â€Å"Lean start-up† strategy. Many start-ups do not manage to survive because they spend a lot of money and time trying to produce products to customers that they might don’t like and therefore will mathematically drive the company out of business ( Eisenman, 2011). The methodology on start-up businesses is all about avoiding waste in terms of money and time. A good example is through the Toyota Production System (Dennis 2002). Important factors, for the success of small firms, especially in recessionary environment are the role of education, training and prior knowledge and experience. There are evidences that prove entrepreneurs having previous experience in the industry and knowledge of the market will have positive impact on the firms (Harada, 2002). A research that took place by Simpson, Tuck and Belammy, 2008, shows that only one group out of the four( â€Å"the empire builder†, â€Å"the happiness seeker†, â€Å"the vision developer† and â€Å"the challenge achiever†) showed clear evidence that education and training had a positive impact on the success of the business. He found out that motivation and teamwork is a key factor for success. According to Fiol (2001) employees are recognised as one of the most valuable resources to the business in order to achieve their objectives. For some small firms the key point for success is happiness. Entrepreneurs must be happy at wor k as well the employees and the customers must enjoy the experience at the place of work (Simpson, Tuck and Belammy, 2008). Analysts have researched on firms choosing to start during recession by following investment strategies. In antithesis with downsizing, firms like to take recessions as opportunities to innovate, expand and invest into new markets in order to extend or expand in a competitive advantage during the recession. Most of today’s household names had successfully launched businesses during recessions in the past. In the oil and steel industries that were emerging during the 1870s recession Rockefeller and Carnegie took advantage of steel production and technologies and of the weakness of various competitors from the same industry (Bryan and Farrell, 2008), and Edison also established General Electric which is until today a big and successful business (Lynn, 2009). Hershey started up their brand and distribution during the 1893-97 depression. Everybody also know until today Kellogg’s which grew out of another period of depression in the 1920s (Rumelt , 2008). The electrical, che mical and motor industries that were very important to post-war British industry expanded during the 1930s. Also two massive companies today, Microsoft and Apple corporations were also both founded in the 1970s, following from the oil-crisis. A lot of different studies disagree that firms adapt to recession conditions by applying business strategies based on new investment, market diversification and innovation, and a a strategy such as that usually leads to higher levels of business performance. Such examples are :targeting new market niches ,increased marketing spending and new product development (Roberts, 2003; Srinivasan, 2005; Pearce II and Michael, 2006); pricing strategies that centre the value, whereby rich resource firms highlight brand and quality instead of low prices to attract customers, or even, adopting ‘acquisitive pricing’ policies, to control low prices in sensitive markets that are influenced by prices (Chou and Chen, 2004). On a macro-level, quantitative studies of quantities and asset prices show that quantities differ more than prices do over the business’s cycle, including time between the periods of recession (e.g. Bhaskar, 1993; Geroski and Hall, 1995). From the above it is referred that most firms respond to macroeconomic shocks from a recession by prices maintenance, leading to quantities sold eventually to decrease. For a lot of firms, this is more likely to consequent into lower sales and, to extreme cases, exit. Studies like this show important data on the response of firm under financial crisis conditions but offer a small insight on why firms pick to respond in this way or if the price maintenance is advised by efficient measures. For the new business, more recent studies claim that a recession is normally an opportunity, not a threat for them, if handled correctly (Rumelt, 2008; Williamson and Zeng, 2009). The recent recession the whole world is facing is characterised by its nature globally and the risk that companies in rising markets take are becoming more active than expected. But research also show businesses not doing very well. Williamson and Zeng (2009) said that a key strategy business might be adopted to avoid this by focusing on developing what rising markets know to do well by offering value for money. They also suggest that companies should invest in research that is aimed at service and product innovation offers similar purposes but at lower expenses and costs. To sum up, a new business has to have a strategy to begin with. The proof on start up businesses adopting investment strategies to grow through recession is not so clear. Taking on strategies in the beginning and especially in a recession is under risk and most businesses are more likely to be very busy with short-term survival to think correctly about way to innovate and grow. Investments need resources –managerial skills, technical expertise and especially finance –and businesses with no or fewer resources are more likely not to be able to implement them. On the other side, history has proved that companies can adapt competitive advantage though a recession period from innovating into services, business models, products and also by getting into new and growing markets. As seen from previous studies they make very little efforts in explaining the reasons why particular firms do so very well when starting up their business in time of recession. No explanation is clearly given why they take the risk in the first place and avoid the potential risks of attempting such investment. It is consequential from the various researches that when a business adopts investment strategies from the beginning, success without any doubt follows. But the procedures a business has to take to imply these investment strategies and also having profitable outcomes is more likely to be more complicated than just said. However, such suggestions ignore the external issues: if all new firms start up by adopting investment strategies, would all succeed? In such crucial times of a recession, when nearly all customers turn to cheaper products, market conditions may not be able to support a wide range of unique and new innovations or a large number of firms looking for diversity, or new business wanting to grow and succeed. It is known that new business cannot lower their costs as they have more expenses than a mature business. REFERENCES Aktas, G.

Ohm’s law Essay

An electronics factory needs resistors of 5 ohms and 15 ohms for a new electrical device. My task is to investigate how the resistance of a piece of wire depends on length and to find the length of the wire needed to make the required resistors, using only 4 volts. Introduction/Planning A selection of different wires made from constantan and nichrome and the usual laboratory apparatus will be available for me. Wire A – Constantan wire of approximate diameter 0. 3mm Wire B – Constantan wire of approximate diameter 0. 4mm Wire C – Constantan wire of approximate diameter 0. 3mm A constantan is an alloy whose resistance stays fairly constant when it becomes hot. In fact the resistance changes by less than 0. 5% even when the temperature rises by a few hundred degrees. Nichrome, along with other metals, is an alloy whose temperature does change appreciably when it becomes hot. Before starting my coursework, I have to find the variables in the experiment, safety aspects etc. I found that a number of things affect the resistance of a wire. Below is a list of factors and reasons why they affect the resistance of a wire. From this list of factors I have to make sure that these factors remain constant or excluded from the experiment. We are only investigating length but the other variables may change our outcomes. In electricity, resistance is the ratio of the potential difference (p. d. or voltage) across a conductor to the electrical current, which flows through it as a result. The unit of measurement is the ohm (O), this being the resistance of a conductor requiring a potential difference of 1 volt across its ends to produce a current of 1 ampere. For a given metal conductor at constant temperature the value is the same whatever the current (Ohm’s law), but rises if the temperature rises. Any conductor possessing resistance gives off heat when a current flows through it. Joule’s law describes this effect. Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. Resistance is a measure of how hard it is to move the electrons through the wire. Ohm’s law: The current flowing through a metal is proportional to the potential difference across it, provided that the temperature remains constant. We are going to use metals, which obey ohm’s law, metals which give us a constant value for resistance (gradient). Resistance (? ) = P. d across the wire (V) / Current through the wire (A) Current flows in an electric circuit in accordance with several definite laws. The basic law of current flow is Ohm’s law, named for its discoverer, the German physicist Georg Ohm. Ohm’s law states that the amount of current flowing in a circuit made up of pure resistances is directly proportional to the electromotive force impressed on the circuit and inversely proportional to the total resistance of the circuit. The law is usually expressed by the formula I = V/R, where I is the current in amperes, V is the electromotive force in volts, and R is the resistance in ohms Ohm’s law applies to all electric circuits for both direct current (DC) and alternating current (AC), but additional principles must be invoked for the analysis of complex circuits and for AC circuits also involving inductances and capacitances. A series circuit as on page 5, is one in which the devices or elements of the circuit are arranged in such a way that the entire current (I) passes through each element without division or branching into parallel circuits. When two or more resistances are in series in a circuit, the total resistance may be calculated by adding the values of such resistances. If the resistances are in parallel, the total value of the resistance in the circuit is given by the formula: In a parallel circuit, electrical devices, such as incandescent lamps or the cells of a battery, are arranged to allow all positive (+) poles, electrodes, and terminals to be joined to one conductor, and all negative (-) ones to another conductor, so that each unit is, in effect, on a parallel branch. The value of two equal resistances in parallel is equal to half the value of the component resistances, and in every case the value of resistances in parallel is less than the value of the smallest of the individual resistances involved. In AC circuits, or circuits with varying currents, circuit components other than resistance must be considered. If a circuit has a number of interconnected branches, two other laws are applied in order to find the current flowing in the various branches. These laws, discovered by the German physicist Gustav Robert Kirchhoff, are known as Kirchhoff’s laws of networks. The first of Kirchhoff’s laws states that at any junction in a circuit through which a steady current is flowing, the sum of the currents flowing to the point is equal to the sum of the currents flowing away from that point. The second law states that, starting at any point in a network and following any closed path back to the starting point, the net sum of the electromotive forces encountered will be equal to the net sum of the products of the resistances encountered and the currents flowing through them. This second law is simply an extension of Ohm’s law. The application of Ohm’s law to circuits in which there is an alternating current is complicated by the fact that capacity and inductance are always present. Inductance makes the peak value of an alternating current lag behind the peak value of voltage; capacitance makes the peak value of voltage lag behind the peak value of the current. Capacitance and inductance inhibit the flow of alternating current and must be taken into account in calculating current flow. The current in AC circuits can be determined graphically by means of vectors or by means of the algebraic equation, in which L is inductance, C is capacitance, and f is the frequency of the current. The quantity in the denominator of the fraction is called the impedance of the circuit to alternating current and is sometimes represented by the letter Z; then Ohm’s law for AC circuits is expressed by the simple equation I = V/Z. We know that all instruments have an error on its measurement, so the way to work out the percentage error is: Percentage error = (error / measured value) i 100 Conduction in metals In metals, atoms contain protons, nucleus and lose electrons which orbit around the nucleus. Below, I have investigated conduction in metals and how they affect resistance. METAL LATTICE (Electrons move in a random direction. ) METAL LATTICE (Electrons with power pack in a particular direction. ) Variables Length: If the length of the wire is increased then the resistance will also increase as the electrons will have a longer distance to travel and so more collisions will occur. Due to this, the length increase should be proportional to the resistance increase. Thickness: If the wire’s thickness is increased the resistance will decrease. This is because of the increase in the space for the electrons to travel through. Due to this increased space between the atoms, there should be fewer collisions. The number of free electrons changes from one material to another. The size of the ions changes from one material to another, this affects the current and therefore affects the resistance. The arrangement and size of the atoms change from one material to another. So if there is a kink in the wire this will change the thickness of the wire. Temperature: If the wire is heated up the atoms in the wire will start to vibrate because of their increase in energy.
