Energy Stored on a Capacitor
This energy is stored in the electric field. A capacitor. =. = x 10^ F. which is charged to voltage V= V. will have charge Q = x10^ C. and will have stored energy E = x10^ J. From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV.
