8.4: Energy Stored in a Capacitor
The space between its plates has a volume Ad, and it is filled with a uniform electrostatic field E. The total energy (U_C) of the capacitor is contained within this space. The energy density (u_E) in this space is simply (U_C) divided by the volume Ad. If we know the energy density, the energy can be found as (U_C = u_E(Ad)).
