Aim: How does the length of a piece of wire affect it's resistance Resistance: It is caused by atoms in the wire preventing the electrons from moving. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. Resistance is measured in ohms (??. To measure resistance we use a voltmeter and an ameter. The formula for resistance is : Voltage / Current = Resistance V/I=R Chins Law says that the resistance will not change providing all of the conditions stay same. The factors that affect resistance is the wire. It could be by it's length, material and thickness. The more resistance there is in a circuit, the lower the current. Resistors are specially designed to provide resistance. They are used in electronics circuits so that the right amount of current is fed to different components to make them work properly. Planning I am going...
