Compute the current density and electron drift speed

Reference no: EM13671658

A small but measurable current of 1.5 x 10^-10 A exists in a copper wire whose diameter is 2.7 mm. The number of charge carriers per unit volume is 8.49 x 10²⁸m^-3. Assuming the current is uniform, Compute the (a) current density and (b) electron drift speed.
