An uncharged capacitor is connected to a battery. While charging the capacitor, how much is the energy lost, from the energy supplied by the battery?

Options

  1. A50 %
  2. B75 %
  3. C100 %
  4. D25 %

Correct answer

D. 25 %

Step-by-step solution

Consider the following diagram: aligned & Q=C V & E_ capocitor = Q^2 2 C = 1 2 C V^2 & W= Work done by battery =Q V=C V^2 & E_ loss =(W)- (E_ capocitor )=C V^2- 1 2 C V^2= 1 2 C V^2= W 2 aligned This is 50 % off the energy supplied by the battery
