Exam-style question
Try this first
What is the primary role of negative feedback in an ideal operational amplifier?.
- A.To increase the overall gain of the amplifier
- B.To stabilize the output and reduce distortion
- C.To amplify the input signal without any loss
- D.To eliminate noise in the circuit
Model answer
What a good answer should say
- To stabilize the output and reduce distortion
Explanation
Why this works
Negative feedback reduces the gain of the amplifier but improves stability and linearity, leading to a more accurate output that closely follows the input signal.
