A wire of radius r = 1mm carries a current of I = 0.314 X 3.2 A. the wire is made from a metal of mass density ρ= 10 gr/cm3, the atomic mass unit of the metal is 60gr. Note that 1 mole of this metal contains 6 X 1023 free electrons, the charge of the electron is e = 1.6 X 10 -19 C. Determine the drift velocity of the free electron using this equation j = -nev
