Question:
What will be drift velocity \(v_d\) of the free electron in a copper wire whose cross sectional area is A = 1.00 mm2 when the wire carries a current of 1.0 A. Assume that each copper atom contributes 1 electron to the electron gas. (Given density of copper = 8.94x103 kg/m3, atomic mass of copper = 63.5 u, 1 u = 1.66x10-27 kg)
