Question: What is the output voltage of an operational amplifier if the non-inverting input is at 2V and the inverting input is at 1V?

Options:

1. 0V
2. 1V
3. 2V
4. Saturation voltage

Correct Answer: Saturation voltage

Solution:

If the non-inverting input is higher than the inverting input, the output will go to saturation, typically the supply voltage.
