Find the energy stored by the capacitor 3F having a potential of 12V across it.(a) 432(b) 108(c) 216(d) 54I have been asked this question during a job interview.This key question is from Method of Images in chapter Electrostatic Boundary Value Problem of Electromagnetic Theory

Answer» RIGHT choice is (c) 216

Easiest explanation: The energy stored in a capacitor is GIVEN by, E = 0.5 CV^2.

E = 0.5 x 3 x 12^2 = 0.5 x 432 = 216 UNITS.
