Physics Coursework Plan The Resistance of a Wire I will be measuring resistance of a wire in two ways. In all procedures I will use different thickness, length and material of wire. This should show if the resistance differs due to any of these variables. Also both experiments will be repeated to try to rule out any anomalies that might occur. There is only a subtle difference between the two experiments, and that is that the equipment used to collect the evidence will be different. For the first experiment I shall use an ammeter to measure the current through the wire in current and a voltmeter to find the voltage across the wire.

Resistance of a Wire
Task
To 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 better conductor. The free electrons are given energy and as a result move and collid…
