Electrical Potentials

Assuming we know the Electric Field, , electrical potential is given as the line integral of the electric field:

We define to be our base potential. Furthermore, to go from to , we take a straight line path, so =

Assuming

=-\int {r{i}}^\infty \vec{E} , dr = -k_{e}q\int_{r_{i}}^{\infty} {\dfrac{1}{r^2}} , dr

= k_{e}q[\dfrac{1}{\infty} - \dfrac{1}{r_{i}}]

V_{f}-V_{i}=k_{e}q[\dfrac{1}{\infty}-\dfrac{1}{r_{i}}]

-V_{i} = -\dfrac{k_{e}q}{r}

V = \dfrac{k_{e}q}{r}
