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(m²) the energy (joules) stored in the condenser is

Options

(a) E² Ad / ?¬ツタ
(b) 1/2 ?¬ツタ E²
(c) ?¬ツタ E Ad
(d) 1/2 ?¬ツタ E² Ad

Correct Answer:

1/2 ?¬ツタ E² Ad

Explanation:

U = 1/2 CV²
U = 1/2 (A ?¬ツタ / d) (Ed)²
= 1/2 ?¬ツタ E² Ad
