Q. A parallel plate condenser has a uniform electric field $E(V/m)$ in the space between the plates. If the distance between the plates is $d(m)$ and area of each plate is $A(m^{2})$ the energy (joules) stored in the condenser is
A) $\frac{1}{2}\varepsilon_{0}E^{2}Ad$
B) $E^{2}Ad/\varepsilon_{0}$
C) $\frac{1}{2}\varepsilon_{0}E^{2}$
D) $\varepsilon_{0}EAd$
Explanation
The correct answer is Option A: $\frac{1}{2}\varepsilon_{0}E^{2}Ad$.
