What will be the gain of the op. amp
Correct answer: A. 1
- A. 1
- B. 2
- C. 3
- D. 4
Explanation
The gain of an ideal operational amplifier (op-amp) in an open-loop configuration is theoretically infinite. In practical terms, it is very high, approaching infinity. Therefore, the gain of an op-amp is often considered to be approximately equal to 1 when operating in an open-loop configuration.Incorrect Options and Explanations: (b) 2 - The gain of an op-amp in open-loop configuration is much higher than 2. (c) 3 - The gain of an op-amp in open-loop configuration is much higher than 3. (d) 4 - The gain of an op-amp in open-loop configuration is much higher than 4.

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.
