# 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 area of each plate is A, the energy stored in the capacitor is: Option 1) Option 2) Option 3) Option 4)

As we learnt in

Parallel Plate Capacitor -

$\dpi{100} C=\frac{\epsilon _{0}A}{d}$

- wherein

Area - A seperation between two plates.

Potential difference the between plates

$V=Ed$

$u = \frac{1}{2}cv^{2} =\frac{1}{2}\left ( \frac{\varepsilon _{0}A}{d} \right )\left ( Ed \right )^{2}$

$u= \frac{1}{2}\varepsilon _{0}E^{2}A.d$
