Question & Answer
Choose the Best Answer
The gain of the op-amp is infinite, which allows for immediate response to input changes.
The feedback mechanism adjusts the input difference to zero, thereby stabilizing the output.
The power supply to the op-amp has reached its maximum limit.
The op-amp's output is saturated, causing it to stop responding to further input changes.
Understanding the Answer
Let's break down why this is correct
When the op‑amp is in a feedback loop, it changes its output so that the voltage at the inverting input matches the non‑inverting input. Other options are incorrect because The idea that the gain is infinite makes people think the output snaps instantly; Some think the output stops because the power supply is full.

Definition
Operational amplifiers (op-amps) are devices that amplify the difference between their two inputs by a large gain factor. They have five terminals, including power supply terminals, inverting and non-inverting inputs, and an output terminal.
