Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat

How does the length of a wire affect its resistance? Introduction: This first report in Physics will show the investigation of how the length of a wire affects its resistance. For starters I will go through the main definitions‚ to get a better knowledge of what is going to happen. However I will plan it out first to show each step of how I started‚ and then go into detail about the results and what the investigation on a whole has showed me. I shall then conclude my findings and present them with

Impact of Peaceful Resistance I think that peaceful resistance impacts society in a positive way. The reason I think this is because the society we live in nowadays shows us that theres a specific way to act or to follow certain beliefs in order to fit in. If people stand up for something they believe that the government is doing wrong then they will show others that it is okay to speak their mind without causing violence. Many people in our history have done this and changed the world.

How Does The Diameter Of Wire Affect The Resistance In A Circuit? Introduction: Some metals such as copper‚ silver and gold are very good conductors of electricity. This is because they all have only one electron on the outer shell. This means that they need only a tiny amount of energy in order to allow the electron to move. Non-metals‚ however‚ do not have free electrons‚ so even non-metals that only have one electron on their outer shell can still hold onto them tightly. Aim Of The Investigation:

How does Length affect resistance? Coursework Aim To find out how the length of a wire can affect resistance. Factors affecting resistance  Temperature  Length of wire  Thickness  Type Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. Resistance is measured in ohms. The symbol for an ohm is Ω Here is the rule for working out the

OBJECTIVE For this piece of coursework I have been asked to investigate into the resistance of wires when the length is changed. INTRODUCTION The objective for my coursework (as already stated above) is to investigate how changing the length of wire can affect the resistance. There are factors which can affect how accurate our expriment is come on four levels. As in any scientific experiment‚ there are always variables ( "likely to change or vary subject to variation; changeable." ) which can

Peaceful resistance to laws positively affects society. By following a law one agrees with it. For the most part laws are just and by following them one can contribute positively to society‚ but there are unjust laws. By following an unjust law simply to prevent personal harm one is agreeing to the terms of the law. In agreeing to the law it is strengthened and others are more likely to follow. It is in this way that “injustice anywhere is a threat to justice everywhere” (Luther) due to the

Does the Mass of a Material Affect it Aerodynamics? There are five basic steps of the scientific method‚ step one is to make observations step two is to come up a hypothesis. Step three is to make a experiment to test the hypothesis‚ step four is to test the hypothesis and step five is to either reject or accept the hypothesis. Scientific method is important because it is a series of techniques that helps you keep track and correct any mistakes‚ and to show others how you got to the result. In

The grinding process is a high energy consumption process. Therefore‚ to improve the grinding and grinding work index is of great significance to dressing plant‚ but also one of the important direction of development of mineral processing technology. There are two effects on the material in the ball mill‚ impact and grinding

How the Length of a Wire Affects Its Resistance In my physics coursework I am going to investigate the effect of the length of a wire on its resistance. Resistance is the measure of how easy it is for current to flow through a wire. Current is the rate of flow of charge through a conductor‚ and it is measured in amps using an ammeter. To help me plan my investigation I have completed a preliminary experiment in which I investigated the effect of the thickness of a wire on its resistance‚ using
