A battery is used to drive a circuit. After a certain amount of time, the current is zero amperes. When the same circuit is driven by an ac generator, the current is non-zero and alternates. Which combination of elements is most likely to comprise the circuit?
A)resistors only
B)inductors only
C)capacitors only
D)a combination of inductors and resistors
E)a combination of inductors and capacitors

A capacitor blocks direct current (DC) after it is fully charged, resulting in zero current with a battery. However, it allows alternating current (AC) to pass through, as the current can alternate and charge/discharge the capacitor.
