You measure the resistivity of the wire in the following way: you connect one end of the wire to one terminal of a battery that has emf 12.0 v and negligible internal resistance. to the other terminal of the battery you connect a point along the wire so that the length of wire between the battery terminals is d. you measure the current in the wire as a function of d. the currents are small, so the temperature change of the wire is very small. part a m . what is the resistivity of the material of which the wire is you plot your results as i versus 1/d and find that the data lie close to a straight line that has slope 600 a made? express your answer in ohm-meters. 0 aed + o ? 12.m
