a) Calculate the drift velocity of electrons in aluminum wire with a diameter of 3.20 mm carrying a 5.0 A current, given that there are three free electrons per aluminum atom. The density of aluminum is 2.70 × 10³ kg/m³ and the atomic mass of aluminum is 27.0 g/mol. [Hint: Current through a wire is given by: I = nqAvq. You may also find the following constants useful: e = 1.6 x 101C, NA = 6.02 x 1023 atoms/mol]
