How length affects the resistance of a wire Introduction This investigation is about how a factor affects the resistance of a wire. During the investigation I will try to find out how the resistance changes and why. For every experiment I do, I will measure the potential difference and the current. With those readings I can work the resistance out using the equation: Resistance is measured in Ohms ( ) Voltage and current are in direct proportion to each other. If one of them is doubled or halved then so is the other. There are number of factors which can affect resistance of a wire. These factors are: * The length * The temperature * The surface area * The width * The cross section surface area * The material * The amount of current or potential difference The factor that I am going to investigate is how length affects the resistance of a wire. I will be keeping all of the other...
