... 24-3: Electric Potential (V): is the potential energy per unit charge. V = U/q DV = DU/q = -W/q V = - W∞/q Note that the work you apply to a charge is the negative of the work that the field applies on the charge (when there is no change in kinetic energy). See the work energy theorem! DV = Wapplie ...
