Question & Answer
Choose the Best Answer
It increases the input impedance and decreases the output impedance.
It ensures the output adjusts to match the input, minimizing distortion.
It amplifies the input signal without any adjustments.
It prevents the op-amp from operating in a linear region.
Understanding the Answer
Let's break down why this is correct
Negative feedback lets the amplifier check its own output and compare it with the input signal. Other options are incorrect because Some think negative feedback mainly changes how much resistance a circuit has; A common belief is that feedback simply boosts the signal.

Definition
Negative feedback in op-amps involves connecting the output back to the input to achieve self-correction. In negative feedback, the ideal op-amp forces the inverting and non-inverting inputs to be equal, maintaining stability and precise control.
