A copper wire has a circular cross-section with a radius of 1.25 mm.
(a) if the wire carries a current of 3.70 A, find the drift speed of electrons in the wire. (Take the density of mobile charge carriers in copper to be n = 1.10 X 1029 electrons/m3.)
(b) For the same wire size and current, find the drift speed of electrons if the wire is made of aluminum with n = 2.11 x 1029 electrons/m3.
