Physics · Amplifiers
In an inverting amplifier, the two input terminals of an ideal Op-amp are at the same potential (virtual ground) because:
- 1The open-loop gain of the Op-amp is infinite✓
- 2The input impedance of the Op-amp is infinite
- 3CMRR is infinite
- 4The two input terminals are directly shorted internally
Correct answer
The open-loop gain of the Op-amp is infinite
