Plot a graph of resistance, R, in Ω on the y-axis against length, l, in cm on the x-axis). Draw the line of best fit. We can see from the graph that as the length of the wire, l, increases ...

A second experiment can be carried out to investigate experimentally how the resistance of a metallic conductor at constant temperature depends on the area of cross section. The above experiment ...
