We have already seen that the electrostatic potential is the potential energy of a unit charge brought from infinity.

Since the force is proportional to the charge we're moving, we can calculate the work per unit charge/ \(W_u\) (so \(W = q W_u\)),

\[ W_u = -\int_{{\bf a}}^{{\bf b}} {\bf E} \cdot d{\bf l} \]
