This article lists 100 Resistor MCQs for engineering students. All the Resistor 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 their fundamentals on Resistor.

Electronic and electric circuits and devices are built with billions of passive and active electronic and electrical components such as resistors, capacitors, inductors, current sources, etc. One among these components is a resistor which is a passive component.

A resistor is designed with two terminals, available in different sizes, shapes, packages, and types depending on the application. Its main purpose is to oppose the current flow in order to protect the electrical or electronic circuits from breakdowns.

The value of resistance is measured in terms of ohms. They are classified as wire wound resistor, special resistor, metal film resistor, variable resistor, network and surface mounted resistor, thick film, thin-film resistor, etc.

These resistors are designed based on applications requirements are deployed as fuses, circuit breakers, alarms, clocks, street lights, etc. They benefit in terms of budget-friendly, zero union potential, simple in design, etc. But lack in resisting high current value.
