25.12. A copper wire has a square cross section 2.3 mm on a side. The wire is 4.0 m long and carries a current of 3.6 A. The density of free electrons is 8.5 X 1028/mº. Find the magnitudes of (a) the cur- rent density in the wire and (b) the electric field in the wire. (c) How much time is required for an electron to travel the length of the wire?
