In the Hall effect, this quantity is transverse to the current. Kirchoff's loop rule states that the sum of this quantity in a loop is 0. Potential energy is equal to charge times this quantity, and across branches of a parallel circuit, this quantity is equal. By (*) Ohm's law, it equals current times resistance. For 10 points, name this quantity,
