The voltage gain of an amplifier with 9% negative feedback is 10. The voltage gain

The voltage gain of an amplifier with 9% negative feedback is 10. The voltage gain without feedback will be

Options

(a) 1.25
(b) 100
(c) 90
(d) 10

Correct Answer:

100

Explanation:

One applies negative feed-back, which reduces the output but makes it very stable. For voltage amplification amplifiers the value of output voltage without the negative feed-back could be very high. The value max shown here is 100.
