Which device can store electrical energy in electric fields?
Correct Incorrect A capacitor consists of two conductive plates separated by an insulator (dielectric). When a voltage is applied across the capacitor, it stores electrical energy in the form of an electric field between the plates. An inductor stores energy in a magnetic field, a resistor resists the flow of current, and a transistor is used for switching and amplifying electrical signals.
