8.4: Energy Stored in a Capacitor
The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.

Energy storage in capacitors
Then it stops. Call this maximum voltage V. The average voltage across the capacitor whilst it''s being charged is (V/2), so the average power being delivered to it is I (V/2). It was charged for T seconds, so the energy stored in the capacitor is T I (V/2). The charge accumulated on the capacitor is Q = I T, so the total energy stored is Q (V/2).
