## Electrical energy stored in a Capacitor

The formula for calculating the Electrical energy stored in a capacitor, basically calculates the work done by the battery. The voltage V is proportional to the amount of charge which is already on the capacitor. The values required for solving this formula are the value of charge in coulombs and the capacitance in farads.

## $$\frac{{q}^{2}}{\mathrm{2c}}$$

The values needed are : q = charge in coulombs and c = capacitance in farads
