A parallel plate capacitor has a uniform electric field ‘ E ‘ in the space between the plates. If the distance between the plates is ‘d’ and the area of each plate is ‘A’, the energy stored in the capacitor is (Epsillon = permittivity of free space)

The capacitance of a parallel plate capacitor is

C=\frac{{{\in }_{0}}A}{d}

Potential difference between the plates is

V = Ed      …….. (ii)

Then, the energy stored in the capacitor is given by:

U=\frac{1}{2}C{{V}^{2}}=\frac{1}{2}{{\in }_{0}}{{E}^{2}}Ad
