A coil of wire is also called:
Correct answer: C. Inductor
- A. Insulator
- B. Semi-conductor
- C. Inductor
- D. All of above
Explanation
The correct term for a coil of wire is Inductor.An inductor, often referred to simply as a coil, is a passive electronic component that stores energy in a magnetic field when an electric current flows through it. It is not called an insulator or a semiconductor.

About Electromagnetic Induction
Changing magnetic flux induces an emf according to Faraday's law, while Lenz's law gives the direction that opposes the change producing it. Transformers apply induction between coils to step alternating voltage up or down, with turns ratio, current transformation and energy losses determining practical operation.
