Question & Answer
Choose the Best Answer
It increases the gain to infinity.
It stabilizes and reduces the gain to a predictable value.
It has no effect on the gain.
It causes the gain to fluctuate randomly.
Understanding the Answer
Let's break down why this is correct
Negative feedback feeds a small portion of the output back to the input in the opposite direction. Other options are incorrect because Some think feedback makes the amplifier stronger, but it actually does the opposite; People sometimes think feedback is unnecessary.

Definition
While op-amps do not have infinite gain in practice, their high gain allows for reliable circuit design using negative feedback. Op-amp gain specifications vary between models, and practical op-amp circuits rely on predictable gain behavior.
