Answer:

capacitors only

Explanation:

When a battery or a DC supply is used to drive a circuit, the current becomes zero after some time. But when an AC generator is used in the same circuit, the current is non-zero and is alternates.

Here, a combination of capacitors are used to drive the circuit.

As we know in capacitor,

current, i = c. dv/dt

where c is capacitance, v is voltage and t is time.

So as in DC voltage, v (voltage) is constant and hence current i = 0.

But in AC voltage, the voltage v varies with time t. Therefore here capacitors are used only.

Capacitors are used to store energy.

Thus the answer is capacitors.
