This energy stored by capacitor can be crucial for applications where quick energy release is required, such as in camera flashes, power supplies, and even in electric vehicles. The formula for energy stored in a capacitor is: where EEE is the energy stored, CCC is the capacitance, and VVV is the voltage across the capacitor.
Energy in a capacitor (E) is the electric potential energy stored in its electric field due to the separation of charges on its plates, quantified by (1/2)CV 2. Additionally, we can explain that the energy in a capacitor is stored in the electric field between its charged plates.
Capacitors are essential components in electronics, widely known for their ability to store energy. This energy stored in a capacitor is what allows these devices to provide quick bursts of energy when needed, stabilize voltage, and manage power flows within circuits.
From the expression of stored energy in a capacitor, it is clear that the energy stored is directly proportional to capacitance of the capacitor, which means a capacitor of higher capacitance can store more amount of energy for the same voltage and vice-versa.
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.
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

5. Since the energy stored in the capacitor has decreased, this implies that work was done on the system. The work done is equal to the change in energy of the capacitor. This work can be thought of as the energy required to insert the dielectric into the capacitor, overcoming the attractive forces between the charges on the capacitor plates.
