Question
What type of electrical component stores energy in a magnetic field?
Answer Options
- A) Varistor
- B) Capacitor
- C) Inductor
- D) Diode
Correct Answer: C
Explanation
The component that stores energy when current flows through it by creating a surrounding magnetic field is the Inductor. This ability to store energy in a magnetic field is called inductance (T5C03).
Inductors are typically constructed as a coil of wire (T6A07) and are used in radio circuits to filter out high frequencies, or in combination with capacitors to create frequency-selective tuned circuits (T6D08).
