January 6, 2023 By WatElectronics

This article lists 100 Inductors MCQs for engineering students. All the Inductors Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Inductors.

Electronic components deal with passive elements such as resistors, capacitors, and inductors which means these elements require external power sources to be provided to operate. An inductor is a coil component which is also called a choke.

The conductor-based material is used for constructing an inductor. The purpose of this is to accumulate the energy generated from the magnetic field. These are large and small type inductors where the small type of inductors are etched onto PCB.

The types of inductors include high-frequency inductors, power supply-type inductors, and general circuit-type inductors. The merits of the inductor include zero losses, minimum cost, at high frequencies minimum losses.

The demerits include minimum Q factor and maximum inductance value. Inductor applications include lightening, power regulation systems, induction motors, and minimum noise operation systems.
