consider a wire made of aluminum with radius of 1 mm. if there is one conduction electron per atom in aluminum, calculate the current density corresponding to the 1mA of current.find the drift speed of conduction electrons for this current.(density of aluminum is 2.70×10^3 kg/m^3 and 1 mole of it has a mass of 26.98 g)
