Energy stored in the large capacitor is used to preserve the memory of an electronic calculator when its batteries are charged. (credit: Kucharek, Wikimedia Commons) Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q and voltage V on the capacitor.
In this condition, the capacitor is said to be charged and stores a finite amount of energy. Now, let us derive the expression of energy stored in the capacitor. For that, let at any stage of charging, the electric charge stored in the capacitor is q coulombs and the voltage the plates of the capacitor is v volts.
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 expression in Equation 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 between its plates.
A simple example of capacitors as an energy storage device is parallel plate capacitors. It is generally referred to as Condenser. In this article, we will discuss the formula and derivation of energy stored in a capacitor.
