A copper wire used for house hold electrical outlets has a radius of 2.5 mm (Imm 10*m). Each Copper atom donates one electron for conduction. If the electric current in this wire is 22.00 A, copper density is 8900 kg m and its atomic mass is 64 u. (lu= 1.66 x 10-27 kg), the electrons drift velocity v in this wire is a) 1.90 x 10 m s., b)8.36 x 10- m/s, c) 1.60 x 104 m/s. d) 1.42 x 104 m/s, e) None of the above.
