For the feedback circuit of voltage series feedback amplifier, find the feedback voltage for the specifications: R1=1kΩ, RF = 10kΩ and Vo= 25v.

For the feedback circuit of voltage series feedback amplifier, find the feedback voltage for the specifications: R1=1kΩ, RF = 10kΩ and Vo= 25v. Correct Answer 2.3v

The feedback voltage, Vf = (R1*Vo)/(R1+RF) = (1kΩ*25v)/(1kΩ+10kΩ) = 2.272v ≅ 2.3v.
