Capacitor charge, energy, capacitance and voltage explained A capacitor consists of two parallel conductive (metal) plates which are separated by special insulating material called a dielectric. When a voltage is applied to the plates one plate is charged positively with respect to the supply voltage, while the other has an equal and opposite. 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) The energy is stored in capacitors that, because of conversion inefficiencies, have to store some 400 MJ.

Energy Stored in a Capacitor. Moving charge from one initially-neutral capacitor plate to the other is called charging the capacitor. When you charge a capacitor, you are storing energy in that capacitor.
