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

Options

  1. A1 2 ₀ V² d²
  2. B1 2 ₀ V² d²
  3. C1 2 C V²
  4. DQ² 2 C

Correct answer

A. 1 2 ₀ V² d²

Step-by-step solution

Energy density = 1 2 ₀ E² Since E= V d Therefore energy = 1 2 ₀ ( V² d² )
