This article lists 30 DC Amplifier MCQs for engineering students. All the DC Amplifier 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 DC Amplifier.

Amplifiers in electronics are one of the most crucial components. To boosts the signal’s level and to enhance the applied signals quality amplifiers are preferred. Fluctuating signals get amplified by Transistor-based amplifiers. Almost every purpose implementation of amplifiers is essential.

Generally, Electronic Amplifiers of signals come in two categories: One that amplifies steady DC Voltages and the other that blocks DC by amplifying Audio & high frequencies. Noise can be rejected using AC Amplifiers whereas DC Amplifiers are preferable for Low-frequency responses.

DC amplifiers are devices where the outcome obtained from one of the stages directly gets coupled to the input of the next stages. Even zero frequency range signals can be accessed. Photoelectric currents or thermocouples make use of these amplifiers.

No coupling devices are needed between output and the incoming stages in Direct Coupled amplifiers. Not only direct currents but also alternating currents can be amplified by using these amplifiers. Zero frequency signal gets amplified using DC amplifier and is only devices suitable for this purpose.
