What is the primary function of a capacitor?

Explanation:
A capacitor’s main role is to store electrical energy temporarily. It does this by creating an electric field between two conductors separated by a dielectric. This lets the capacitor supply or absorb short bursts of current, help smooth voltage levels, and filter signals in a circuit. It’s not meant for permanent energy storage—the energy can be delivered quickly when needed, but it isn’t stored for long periods like a battery. Converting AC to DC requires rectifiers, and regulating current is handled by other components or regulators; a capacitor by itself doesn’t perform those functions.
