The overall gain of a multistage amplifier is 100. When negative feedback is applied, the gain reduces to 10 . Find the fraction of the output that is feedback to the input.

View answer and explanation

Correct option: C

0.09

Option C (0.09) is correct because the fraction of the output that is fed back to the input is 0.09, calculated using the formula for gain with negative feedback.
