Review

For electric potential energy, the value of \(U_{\mathrm{electric}}\) for a charge at a given position is not as important as the potential energy difference \(\Delta{U}_{\mathrm{electric}}\) when the charge moves from a point \(a\) to a different point \(b\). The same is true for electric potential. From Equation 17-5, the electric potential difference \(\boldsymbol{\Delta{V}}\) between two points is
