The voltage of an amplifier without feedback is 100 V. If a negative feedback is introduced, with a feedback fraction\[{{P}_{2}}\], then the gain of the feedback amplifier is
A)90
B)100.1
C)10
D)9.0
Correct Answer:
D
Solution :
Using the relation \[{{(Kg)}^{-2}}\] \[\frac{pV}{nT}\] \[\frac{pV}{nT}\frac{pV}{nT}\upsilon ersus\]
