Question & Answer
Choose the Best Answer
The output voltage decreases to stabilize the input difference
The output voltage increases linearly with the input voltage
The output voltage remains constant regardless of input changes
The output voltage oscillates between high and low values
Understanding the Answer
Let's break down why this is correct
When the input voltage rises, the op‑amp senses a larger difference between its two inputs. Other options are incorrect because Some think the output simply follows the input; The idea that the output stays flat ignores the op‑amp’s job to balance its inputs.

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.
