Capacitors are sometimes used in dc circuits to

Explanation:
Capacitors in DC circuits are used to smooth out small fluctuations in voltage or current. They act as a temporary energy reservoir, charging when the voltage rises and discharging when it falls, which reduces ripple from sources like rectifiers. In steady-state DC, a capacitor blocks DC current, but it responds to changes, helping keep the voltage steadier when there are transient pulsations. While capacitors do store energy, their primary role here is to smooth the DC output rather than to step voltage up or down or to counter inductive reactance, which is an AC-related concern.
