an aluminium wire having a cross-sectional area A = 4 x 10^-6 m^2 carries a current I = 5 A. find the drift speed (vD) of the electrons in the wire. The density of aluminium is 2.7 g/cm^3 and its molar mass = 27 g/mol. Assume that one conduction electrons is supplied by each atom. Avogadro's constant is 6.023 x 10^23 atom/mole and e = 1.6 x 10^-19 C.
