What electrical component stores energy in an electric field?
- A.Resistor
- B.Capacitor (correct answer)
- C.Inductor
- D.Diode
WhyA capacitor is the electrical component that stores energy in an electric field. A capacitor stores energy in the electric field that forms between its two conductive plates when a voltage is applied, answer B. A resistor (A) dissipates energy rather than storing it, an inductor (C) stores energy in a magnetic field instead, and a diode (D) is a one-way current valve, not an energy-storage device.
