Question
What electrical component stores energy in an electric field?
Answer Options
- A) Varistor
- B) Capacitor
- C) Inductor
- D) Diode
Correct Answer: B
Explanation
The component that stores energy by building up an electrical charge on two conductive surfaces separated by an insulator is the Capacitor (T6A05). The energy is stored in the electric field that develops between these two charged plates.
Capacitors are essential in radio circuits for filtering, coupling (passing AC while blocking DC), and in combination with inductors, for frequency tuning (T6D08). The ability to store energy in an electric field is called capacitance (T5C01).
