Current Electricity

A current of \(10 \mathrm{~A}\) is passing through a metallic wire of cross-sectional area \(4 \times 10^{-6} \mathrm{~m}^2\). If the density of the aluminium conductor is \(2.7 \mathrm{~gm} / \mathrm{cc}\) considering aluminium gives 1 electron per atom for conduction, then find the drift velocity of the electrons if molecular weight of aluminium is \(27 \mathrm{~gm}\).
