Energy per unit volume for a capacitor having area A and separation d kept at potential difference V is given by

Multiple Choice Options

  • A 12ϵ0V2d2\frac{1}{2}\epsilon_0\frac{V^2}{d^2}
  • B 12ϵ0V2d2\frac{1}{2\epsilon_0}\frac{V^2}{d^2}
  • C 12CV2\frac{1}{2}CV^2
  • D Q22C\frac{Q^2}{2C}.

Step-by-Step Verified Solution

Energy stored per unit volume = 1 2 _ 0 E 2 = 1 2 _ 0 ( V d ) 2 = 1 2 _ 0 V 2 d 2     ( _ E = V d )
