The energy stored in a capacitor is the work required to charge the capacitor, beginning with no charge on its plates. The energy is stored in the electrical field in the space between the capacitor plates. It depends on the amount of electrical charge on the plates and on the potential difference between the plates.
Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q and voltage V on the capacitor. We must be careful when applying the equation for electrical potential energy ΔPE = q Δ V to a capacitor. Remember that ΔPE is the potential energy of a charge q going through a voltage Δ V.
The total work W needed to charge a capacitor is the electrical potential energy U C U C stored in it, or U C = W U C = W. When the charge is expressed in coulombs, potential is expressed in volts, and the capacitance is expressed in farads, this relation gives the energy in joules.

The energy stored in a capacitor is nothing but the electric potential energy and is related to the voltage and charge on the capacitor. If the capacitance of a conductor is C, then it is initially uncharged and it acquires a potential difference V when connected to a battery. If q is the charge on the plate at that time, then
The work done is equal to the product of the potential and charge. Hence, W = Vq If the battery delivers a small amount of charge dQ at a constant potential V, then the work done is Now, the total work done in delivering a charge of an amount q to the capacitor is given by Therefore the energy stored in a capacitor is given by Substituting
To be sure, the battery puts out energy QV b in the process of charging the capacitor to equilibrium at battery voltage V b. But half of that energy is dissipated in heat in the resistance of the charging pathway, and only QV b /2 is finally stored on the capacitor at equilibrium.
