- A metal wire has a circular cross section with radius 0.800 mm.You measure the resistivity of the wire in the following way: You connectone end of the wire to one terminal of a battery that has emf 12.0 Vand negligible internal resistance. To the other terminal of the batteryyou connect a point along the wire so that the length of wire betweenthe battery terminals is d. You measure the current in the wire as a functionof d. The currents are small, so the temperature change of the wireis very small. You plot your results as I versus 1/d and find that the datalie close to a straight line that has slope 600 A . m.
