Problem

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: (2021, 2012 Mains, 2011 pre, 2008) (

\epsilon_0

= permittivity of free space) a.

\epsilon_0 E A d

\frac{1}{2} \epsilon_0 E^2 A d

\frac{E^2 A d}{\epsilon_0}

\frac{1}{2} \epsilon_0 E^2
