Answer» Correct Answer - B The fact that electrons flow from one elctrode to the other indicates that there is a potential (or voltage) difference between the two electrodes. This potential difference between the electrodes, called the electromotive froce, or `emf(E)`, is most conveniently described as potential, which is the potential energy per unit charge. We measure this quantity in volts. The volt `(V)` is the `SI` unit of potential difference. The electrical work expended in moving a charge through a conductor is Electrical work = charge `xx` potential difference Corresponding `SI` units for the terms in the terms in this equationare Joules = coulombs `xx` volts
