Physics Coursework: Current in a Wire Current: Current is a flow of electrons around a circuit. Current will only flow through a component if there is voltage across the component. Resistance: This is the movement of electrons through a circuit, which are resisted by the atoms, particles and compounds in a wire, which the current passes through. Wire with small resistance Wire with Large Resistance Variables In this experiment there are number of different variables in this experiment. * Length of wire * Width of Wire * Amount of power going through the wire * Different types of wire For this experiment I have decided to change the length of the wire and measure the amount of current going through the wire to get my results and table. The wire I will use will be copper, this will not change, to have more than one variable would obviously be pointless because there would be no way of determining the factor that is...
