To investigate how the resistance of a wire is affected by various factors The rate at which electricity flows through a circuit is affected by the resistance of the components and/or wires in the circuit. Increased resistance results in a decrease in the amount of current that will flow through the wire. Good conductors tend to result in low resistance while poor conductors (insulators) result in high resistance. Section 1: Planning The purpose of this investigation is to look at the main factors that are responsible for affecting the resistance of a wire in an electric circuit. I have decided to look at four different factors: * The material * The temperature * The cross-sectional area * The length From the equipment available, I have concluded that it could not be possible to investigate how temperature affects the resistance of a wire, as there are no thermometers or any other ways of measuring temperatures. Also, it would...
