The voltage gain of an amplifier with 9% negative feedback is 10. The voltage gain without feedback will be
Options
(a) 90
(b) 10
(c) 1.25
(d) 100
Correct Answer:
100
Explanation:
Negative feedback is applied to reduce the output voltage of an amplifier. If there is no negative feedback, the value of output voltage could be very high. In the option given, the maximum value of voltage gain is 100. hence it is the correct option.
