Resistance of a wire (GCSE corsework)

Does Increasing the Length of a Nichrome Wire Affect its Resistance? Introduction In this experiment I am going to see weather the thickness of wire will affect the resistance of a wire. I will also be seeing weather different lengths of wire effect the resistance of the wire. I will be setting up the wire to a circuit and will be using a ammeter and volt metre to record my results. Background information Electric current …

…times using a low, high and medium setting controlled by using a variable resister. The voltmeter and ammeter had digital scales and therefore giving accurate readings that were read without as little human error possible. Further work which could be done to support prediction? What would be the benefits of further work? How would it develop the understanding of the principles of resistance and wires? Where might this understanding be used in a practical situation?
