Capacitive Reactance [Click Here for Sample Questions] A capacitor is an electronic component that stores electrical energy. In a DC circuit, a capacitor charges until it reaches full capacity and then effectively blocks current flow. In an AC circuit, a capacitor allows current to flow but opposes it, a phenomenon known as capacitive reactance.
