Energy per unit volume for a capacitor having area A and separation d

1.	Energy per unit volume for a capacitor having area A and separation d kept at potential diffeence V is given by : -A. `(1)/(2)epsilon_(0)(V^(2))/(d^(2))`B. `(1)/(2epsilon_(0))(V^(2))/(d^(2))`C. `(1)/(2)CV^(2)`D. `(Q^(2))/(2C)`
Answer» Correct Answer - A Energy density `=(1)/(2)epsilon_(0)E^(2)` Since `E=(V)/(d)` Therefore, energy density `=(1)/(2)epsilon_(0)((V^(2))/(d^(2)))`
