A parallel plate capacitor has a uniform electric field $\overrightarrow 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 : ($\varepsilon $0 = permittivity of free space)

Question

A parallel plate capacitor has a uniform electric field $\overrightarrow 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 : ($\varepsilon $₀ = permittivity of free space)

${{{E^2}Ad} \over {{\varepsilon _0}}}$

${1 \over 2}{\varepsilon _0}{E^2}$

${\varepsilon _0}EAd$

${1 \over 2}{\varepsilon _0}{E^2}Ad$
