The function of a capacitor in an electric circuit is to? A. measure the amount of current in the circuit. B. increase circuit power .C. allow current flow between its plates. D. store electric charges.
B). No. The power delivered to the circuit is determined by the battery or power supply and all the things in the circuit that dissipate energy. A capacitor doesn't do any of these things.
C). No. If any current actually flows between its plates, the capacitor is shot and can't do its job, and must be replaced.
D). Yes. A capacitor stores charges on its plates, and electrical energy in the field between its plates.
