Answer» Correct Answer is: C) Proportional to the square of potensial difference Total electric energy absorbed is given by work done. - W = Q.V W = It.V W = (V/R) Vt W = V2 t/R As R remains constant, W ∝ V2 Therefore, absorbed electric energy is directly proportional to square of potential difference. |
