Question: What is the output voltage of an operational amplifier when the input voltage is zero and the op-amp is powered?

Options:

1. 0V
2. Positive saturation voltage
3. Negative saturation voltage
4. Depends on the circuit configuration

Correct Answer: Depends on the circuit configuration

Solution:

The output voltage of an operational amplifier with zero input voltage depends on the circuit configuration and can be in saturation.
