For a metal that has an electrical conductivity of 7.1107(m)1, do the following: (a) Calculate the resistance (in ) of a wire 2.6mm in diameter and 6.7m long. (b) Calculate the current (in A) if the potential drop across the ends of the wire is 0.060V. (c) Calculate the current density (in A/m2 ). (d) Compute the magnitude of the electric field (in V/m ) across the ends of the wire. (a) (b) A (c) A/m2 (d) V/m
