Question

Quizplus · Accepted Answer

Capacitors are primarily used for storing electrical energy temporarily and can smooth out fluctuations in electrical current, such as pulsing current, by charging and discharging rapidly. This makes them useful in filtering applications where they help to smooth out the output of power supplies.
