Factors Affecting the Resistance of a Metal Wire Introduction: The aim of this investigation is to discover how a variable affects the resistance of a wire. The variables I could test are: 1. Width of a wire 2. Length of a wire 3. Temperature of a wire 4. The material of the wire. I have chosen to test how the length of a wire affects the resistance of it. This is because I believe I can most easily obtain a wide range of results. I decided against testing the width and temperature because the results are difficult to measure and therefore, my investigation may not be reliable. I shall keep the material of the wire constant so as to maintain reliable results. In this experiment, I shall use Ohms Law to work out the resistance of wire, as resistance is measured in Ohms. The formula I shall use is R= V/I. To...
