    In comparing wires of identical shape and carrying the same current but made of different metals, is the drift velocity in each wire inversely proportional to the number density of charge carriers? No. The drift velocity is the same for all conductors. Yes. To have the same current from k times as many carriers, it takes k times the drift speed. No. The drift velocity is directly proportional to the number density of carriers. Yes. To have the same current...
