A parallel plate condenser has a uniform electric field $\displaystyle \mathrm{E}(\mathrm{V} / \mathrm{m})$ in the space between the plates. If the distance between the plates is d(m) and area of each plate is $\displaystyle \mathrm{A}\left(\mathrm{m}^2\right)$ the energy (joules) stored in the condenser is :
Official answer
(1)
$\displaystyle \frac{1}{2} \epsilon_{\mathrm{o}} \mathrm{E}^2 \mathrm{Ad}$
