How does negative feedback affect the gain of an operational amplifier?.
- A.It increases the gain significantly.
- B.It stabilizes the gain and reduces distortion.
- C.It has no effect on the gain.
- D.It only affects the output voltage.
Model answer
What a good answer should say
- It stabilizes the gain and reduces distortion.
Explanation
Why this works
Negative feedback in op-amps reduces the overall gain but stabilizes it, leading to lower distortion and improved linearity in signal processing.
