Doubling the potential across a given capacitor causes the energy stored in that capacitor to reduce to: a. one-half.
b. double.
c. reduce to one-fourth.
d. quadruple.

Explanation:

The stored energy varies with the square of the electric charge stored in the capacitor. If you double the charge, the stored energy in the capacitor will quadruple or increase by a factor of 4.
