# Find the value of feedback ratio.

## If an amplifier has an output voltage of 0.98 V, then what will be value of feedback ratio if its feedback voltage is 0.10 with an increment of voltage gain 200 ?

a. 0.1 & 10

b. 0.20 & 50

c. 0.1 & 0.20

d. 0.1 & 20

Correct Answer : d. 0.1 & 20

**Explanation :**

Estimation of feedback ratio (β) =Vr / Vo and Vf = Voltage gain * feedback ratio.
