The electrical potential energy stored in the electric field of the charged capacitor is commonly shown as. EC = CV2 2 E C = C V 2. The relationship between voltage, capacitance, and charge for a capacitor is. V = Q C V = Q C. Substituting this in the previous equation we obtain. EC = Q2 C E C = Q 2 2 C.
This work becomes the energy stored in the electrical field of the capacitor. In order to charge the capacitor to a charge Q, the total work required is. W = ∫W (Q) 0 dW = ∫ Q 0 q Cdq = 1 2 Q2 C. W = ∫ 0 W ( Q) d W = ∫ 0 Q q C d q = 1 2 Q 2 C. Since the geometry of the capacitor has not been specified, this equation holds for any type

Unfortunately, the energy density of dielectric capacitors is greatly limited by their restricted surface charge storage [8, 9].
