E)increasing or decreasing voltage.

Question

Quizplus · Accepted Answer

Capacitors can help smooth out pulsed or intermittent current in a circuit. When a capacitor is placed in a circuit, it charges up as current flows through it, and then discharges when the current stops flowing. This can help to even out spikes or dips in the current, providing a more consistent flow of electricity. Capacitors are commonly used in power supplies, audio amplifiers, and other types of electronic circuits.
