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

How Does The Legnth Of A Wire Affect Resistance In A Circuit? Physics Investigation Aim: To measure how the length of a wire affects the amount of resistance when an electrical current is passed through it. Background Information: What is an electrical current When a full circuit is created (i.e. a continuous loop has been made connecting the negative end of an electrical source to the positive) it creates a path for electrons to pass through. These electrons need a "push"

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

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

will set up a simple circuit to be able to read the voltage and current when the length of wire changes‚ so I then can work out the resistance. I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. I will not go above 1m or below 0.20m because it may be too long that they resist so much current that the wire burns‚ or the length of the wire is so small that it doesn’t resist any current at all. The length of the wire will be changed by

Current and Resistance Physics Investigation Aim: Investigate how the length of a wire affects the current and resistance of a wire. Prediction and Hypothesis: I think as you increase the length of the Constatan wire‚ you also increase the amount of resistance. The current is the flow of electrons; the current is dependent on the amount of voltage‚ which is applied. Voltage is the push given to the current. The current has to go through a circuit‚ which contains resistance so if you increase

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

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:

Investigation: how the resistance in a circuit varies with the length‚ thickness and type of wire Introduction A current is a flow of negative electrons around a circuit or electrical pathway. This is measured in how many electrons per second or the charge they are carrying go round the circuit (amps or amperes) Voltage or Potential Difference measures how much energy individual electrons have to use up as they go around a circuit. (Volts) Components in a circuit have a Resistance value which
