Question
The drift speed in a copper wire is 7.15 x 105 m/s for a typical electron current. Calculate the magnitude of the electric field E inside
the copper wire. The mobility of mobile electrons in copper is 4.5 x 10-3 (m/s)/(N/C). (Note that though the electric field in the wire is
very small, it is adequate to push a sizable electron current through the copper wire.)
