What type of electrical current do capacitors primarily deal with?

• A. DC only
• B. AC only
• C. Both AC and DC
• D. Neither AC nor DC

Answer: (C)

Capacitors primarily handle both AC and DC currents, which is why the answer is correct. In direct current (DC) circuits, capacitors can store and release energy, allowing them to smooth out voltage fluctuations and act as filters. When a DC voltage is applied, the capacitor charges up to that voltage and remains charged until the circuit is interrupted. In alternating current (AC) circuits, capacitors play a significant role in power factor correction and energy storage as they continually charge and discharge with the alternating voltage. This characteristic makes them essential components in filtering out noise and stabilizing voltage levels in AC applications. Thus, capacitors are versatile components used across a variety of electrical systems, capable of interfacing with both types of current effectively.
