Question
What is the ability to store energy in a magnetic field called?
Answer Options
- A) Admittance
- B) Capacitance
- C) Resistance
- D) Inductance
Correct Answer: D
Explanation
The ability of an electrical component (an inductor or coil of wire - T6A06) to store energy in the form of a magnetic field is called Inductance. This storage property is related to how the component opposes any sudden change in the current flowing through it.
Inductance is measured in Henrys (T5C04) and is a critical component in many radio circuits, often used for filtering and creating tuned circuits when combined with capacitance.
