This article lists 100+ Resistors MCQs for engineering students. All the Resistor's 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 Resistors.

Resistors are passive electronic and electrical components that provide electrical resistance within a circuit like a circuit element. These components include two terminals which are used to divide the voltage, decrease the flow of current & regulate the level of signal level. The resistor works on the principle of Ohms law. This law defines that the voltage in the circuit is directly proportional to resistance & the current supplies within a circuit. The unit of the resistor is ohm denoted with ‘Ω’.

There are different types of resistors available in the market where the working principle is the same for all the resistors but the main difference is their voltage, current, power, and the material type used to make. Resistors are available from micro ohm (µΩ) to mega (MΩ).
