  • Resistance Of A Length Of Wire
    1,426 words
    GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a WireTaskTo investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor, in this case wire, by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor, i.e. it has less resistance. For example, gold has more free electrons than iron and, as a result, it is a bette...

    3,183 words
    The four factors that affect the resistance of a piece of wire: Length, Diameter or thickness, Temperature and The type of metal. From thinking about how I would do this investigation and the outcome of it, I decided to use the length of the wire as the variable. Aim The aim of my investigation is to investigate how length affects the resistance of a length of wire Resistance is the force, which opposes the flow of an electric current around a circuit so that energy is required to push the charg...
  • Wire The Resistance
    1,084 words
    Resistance coursework Aim: My aim is to find out which factors affect the resistance of wire and how they affect them. Ohm's Law: Ohm's law is also relevant to know of Ohm's Law, which states that the current through a metallic conductor (e.g. wire) at a constant temperature is proportional to the potential difference (voltage). Therefore V, I is constant. This means that the resistance of a metallic conductor is constant providing that the temperature also remains constant. Furthermore, the res...
  • Resistance Of Wire
    317 words
    A imI am going to be studying the resistance of wire. The purpose of this investigation is to see how the length of wire affect the dependent variable, resistance. Prediction I predict that, as the length of the wire doubles, the resistance will also double, This means that the length will affect the resistance. Hypothesis Resistance is caused by electrons bumping into ions. If the length of the wire is doubled, the electrons bump into twice as many ions so there will be twice as much resistance...

  • Two Readings For The Same Wire Length
    1,434 words
    IF YOU INCREASE THE VOLTAGE - MORE CURRENT WILL FLOW. IF YOU INCREASE THE RESISTANCE - LESS CURRENT WILL FLOW (UNLESS YOU INCREASE THE VOLTAGE). ' 'o'In Metals The Current Is Carried By Electrons 1. Electric current will only flow if there are charges, which can freely move. 2. Metals contain a sea of 'Free Electrons' (which are negatively charged). And flow throughout the metal if they are given energy. 3. This is what allows electric current to flow so well in materials. ' 'o'Resistance Resist...

    A. Planning Plan of the method to be used: - The resistivity of nichrome can be determined using the equation = RA / L Where: R: - Is the resistance of the wire in "ohms" and can be determined using the equation R = V / I where "V" is voltage in volts and "I" is current in amperes. L: - Is the length of the nichrome wire used in metres. A: - Is the cross-sectional area of the wire in metres square and can be determined using the equation A = d 2 where "d" is the diameter of the wire. If I plot a...
  • Resistant Wire
    962 words
    Aims and hypotheses This investigation is designed to look into the resistance of different material in the form of wires and their conducting capability in different shapes. In order to do so, the materials are to be tested for their resistance in the shape of wires, and the hypotheses are such that different thickness and length of the wire and the material that makes up the wire itself will affect the electric conduction capability. Hence, the factors are: The thickness of the wires: 1, 2, 3 ...

    Investigating the effect of the length of wire on the current in a circuit Physics Coursework Plan I am going to set up the apparatus as shown in the diagram. I will measure the current with varying lengths using an ammeter. To keep it a fait test I will maintain the wire the same thickness and make sure the voltage is constant using a voltmeter. To make the experiment accurate, I will perform it 3 times, recording all 3 sets of results. The length of wire I use will be form 5 cm to 45 cm. Befor...

  • Wire Length
    678 words
    Detailed method: - I set up the circuit as shown in the diagram that I have drawn. I started the experiment by taping a meter ruler between the terminal blocks P, Q so that I could measure 100 cm of nichrome wire. I made sure that the wire was carefully tightened at both terminals to try to minimise the kinks or twists in the wire. I then switched on the power pack supply and adjusted the variable resistor until a constant current of 0.2 A was flowing through the circuit. I then recorded the cor...
