Question & Answer
Choose the Best Answer
The op-amp has infinite gain
Negative feedback is improperly applied
The power supply voltage is too high
The circuit is operating in the linear region
Understanding the Answer
Let's break down why this is correct
When negative feedback is used, the op‑amp compares its output to its input and adjusts to keep the error small. Other options are incorrect because Some think an op‑amp has infinite gain; The belief that a high supply voltage will lower the output is a misconception.

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.
