Have a little read: ... Does the Length of a Wire Affect the Resistance? The aim of this experiment is to find out if the resistance of a piece of wire will change if we vary the length. To do this I will set up a circuit that will include an ammeter, a voltmeter and a piece of wire. The wire will be a different length each time. I think that there will be more resistance on a longer piece of wire - the longer the wire, the higher the resistance. This will happen because of the amount of particles inside the wire that the flow of electrons will need to pass. In turn, there will be more collisions between the electrons and the atoms inside the wire. This is the resistance. A higher resistance will mean more collisions. To succeed, I will need to keep the temperature below a certain level as if
