Energy Stored in Electric Fields: The energy stored in a capacitor is UE = CAVC² We can understand this since it takes energy to push charges of the same sign together on each plate. However, we can also think of this energy as being stored in the electric field created between the plates. 3. Consider a air-filled parallel plate capacitor with plates of area A and gap width H. There is a voltage difference AVC between the plates. For a parallel plate capacitor the capacitance is UE ==CAV² = C = € A H UE = UE/Volume = H and AVC = EH. a.
