The energy stored in a capacitor is directly proportional to
A)the voltage across the capacitor.
B)the charge on the capacitor.
C)the reciprocal of the charge on the capacitor.
D)the square of the voltage across the capacitor.
E)None of these is correct.

Question

Quizplus · Accepted Answer

The energy stored in a capacitor is given by the equation U = 1/2CV^2, where U is the energy stored, C is the capacitance, and V is the voltage across the capacitor. Thus, the energy stored is proportional to the square of the voltage across the capacitor.
