If we want to describe work, we must have
an action which causes no movement or reaction.
a force and a movement in the opposite direction of the force.
a force and a movement in the same direction as the force.
an action which causes movement and an opposite reaction.

C) a force and a movement in the same direction as the force

The answer is 12, for the points

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
