Measuring the Resistivity of a Wire Student Worksheet
where ρ is the resistivity of the metal from which the wire is made, l is the length of the wire and A is its cross-sectional area. Using the circuit below, you will make measurements of current and voltage for different lengths of wire. You will plot a graph of resistance against length and from this you will calculate the resistivity. V zero ...
