Coils of various dimensions designed to introduce specified amounts of inductance into a circuit are called (a) semiconductors (b) superconductors (c) electromagnets (d) inductons

Answer: d) Inductors

Explanation: Inductors are the electric component commonly known by the name of coils as well. The work done by inductors is when the electric current flows through the coils of the wire then there is production of the magnetic field. They are the component that have the inductance in particular amount according to the circuit. So, coils of various dimensions are designed to introduce specified amount of inductance into a circuit are called inductors.
