If the feedback voltage and the output voltage are given as 10v and 4v. Find the gain of the feedback circuit in voltage-series feedback amplifier?
A. 2.5v
B. 40v
C. 3v
D. 6.2v
Answer:A
If the feedback voltage and the output voltage are given as 10v and 4v. Find the gain of the feedback circuit in voltage-series feedback amplifier?
A. 2.5v B. 40v C. 3v D. 6.2v
Explanation: Gain of feedback, B = Vf /Vo = 10v/4v = 2.5v.
