Resistance of Wire

Aim: - In this experiment I will be finding out the resistance of a wire in which its length is the variable. I will be investigating the process of how much the resistance changes due to the increase of the length of the wire (constant wire).
Electrical Current
Electric current is the rate of charge flow past a given point in all electric circuit, measured in coulombs/seconds, which is named amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is constant so that the current in the circuit is related to voltage and resistance by Ohm's law.
