The output voltage becomes equal to the input voltage
B
The output stabilizes to a specific value determined by the feedback network
C
The gain of the op-amp increases significantly
D
The op-amp enters saturation mode
Understanding the Answer
Let's break down why this is correct
Answer
Negative feedback makes the op‑amp drive its output so that the voltage difference between its two inputs is driven toward zero. As a result, the output changes in a way that counteracts any deviation, producing a stable, amplified version of the input signal. This linearizes the amplifier’s behavior and fixes its effective gain. For example, if the non‑inverting input is 1 mV higher than the inverting input, the feedback will push the output to a voltage that forces the two inputs to equalize.
Detailed Explanation
Negative feedback takes a portion of the output and sends it back to the inverting input. Other options are incorrect because Some think the output simply copies the input voltage; A common mistake is to believe feedback makes the gain larger.
