Semiconductor Electronics Materials Devices and Simple Circuits - Result Question 72
74. The voltage gain of an amplifier with $9 %$ negative feedback is 10 . The voltage gain without feedback will be
(a) 90
(b) 10
(c) 1.25
(d) 100

Show Answer
Answer:
Correct Answer: 74. (d)
Solution:
- (d) 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 options given, the maximum value of voltage gain is 100 . Hence it is the correct option.
