What is the open-loop gain of an ideal operational amplifier?.
- A.Infinite
- B.Zero
- C.One
- D.Ten
Model answer
What a good answer should say
- Infinite
Explanation
Why this works
The open-loop gain of an ideal operational amplifier is considered to be infinite, meaning that even a very small input voltage will produce a very large output voltage, leading to saturation. This characteristic is fundamental to the operation of op-amps in various applications.
