Nura Hassan The resistance of wire Introduction Aim: to investigate the resistance of a steel wire (100cm) I am going to measure the resistance of a wire in a circuit by using a voltmeter, ammeter or a multimeter. I am going to use a steel wire that is 100cm connecting to a circuit. The resistance is a component that resists the flow of an electrical current. The greater the resistance of a component, the smaller the current that will flow through a given potential difference, therefore in this experiment the potential difference is the wire and the longer the wire the greater the resistance. This is because in "modular science by Hirst, Hiscock, sang and stirrup", I have read that the potential difference (p.d is the voltage between two points which can make a current between them). So the potential difference and the current will affect the resistance of the wire. To measure resistance we can use...
