Operational amplifier can be used as
Correct answer: D. All of these
- A. inverting amplifier
- B. non-inverting amplifier
- C. comparator
- D. All of these
Explanation
Operational amplifiers (op-amps) are versatile devices and can be used for various applications, including inverting and non-inverting amplifiers, comparators, integrators, differentiators, and more. They are known for their high gain and versatile configurations.Incorrect Options and Explanations: (a) inverting amplifier - This is a correct use of an operational amplifier. (b) non-inverting amplifier - This is a correct use of an operational amplifier. (c) comparator - This is a correct use of an operational amplifier.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
