Which component stores electrical energy in an electric field?
- Resistor
- Inductor
- Capacitor
- Transformer
Answer: Capacitor
Capacitor stores energy in electric field between two conductive plates separated by dielectric. Measured in Farads. Applications: filtering, timing circuits, power factor correction, energy storage. Inductor stores energy in magnetic field; resistor dissipates energy as heat; transformer transfers energy between circuits via electromagnetic induction.
