A cylindrical aluminum wire of diameter d=0.975 mm runs electric current I=7.54 A. Find the drift velocity vd of conduction electrons corresponding to this current: vd=mm/s. What is the strength E of the electric field in the wire that causes this current?: E=V/m. To make things certain, let us use aluminum's mass density of 2.7 g/cm3 and resistivity ρ=2.82×10−8Ω⋅m. The atomic mass of aluminum is 4.48×10−26 kg. You can assume that each atom supplies one conduction electron.
