Factors affecting the resistance of a wire Aim My aim is to find out how the length of a wire and its cross-sectional area, affect the resistance of the wire. Introduction In this investigation I will be finding out what factors affect, and how they affect, the resistance of a wire. The factors I have chosen to test are: * The length of the wire tested * The cross-sectional area of the wire * The material the wire is made of I have chosen these factors as they are easy to test in the school lab, where I will be able to use simple apparatus to make my investigation. The resistance of a wire, or its resistivity, is a measure of how much a wire prevents the flow of electrons within it. The higher the resistance, the harder it is for electrons to flow through the wire, and the lower the resistance, the easier it is for electrons to flow...
