Which of the following electronic components is designed to store electrical energy in an electric field?
- AInductor
- BCapacitor
- CResistor
- DDiode
Show answer & explanationAnswer & explanation
Correct answer: B. Capacitor
A capacitor is an electronic component that stores electrical energy in an electrostatic field between two conductive plates separated by a dielectric material.
Why the other options are wrong
- A. An inductor stores energy in a magnetic field.
- C. A resistor opposes current flow and dissipates energy as heat.
- D. A diode allows current to flow primarily in one direction.
Capacitor
A passive two-terminal electrical component used to store energy electrostatically in an electric field.
- Consists of two conductive plates separated by a dielectric insulator.
- Measured in Farads (F).
- Blocks DC current (after charging) and passes AC current.
Memory trick: CIRcuits have Capacitors, Inductors, and Resistors.
