  1. The voltage transfer ratio V2/ V1 for the network shown in the figure is ________
    1. 0
    2. 2 / 13
    3. 1
    4. 13 / 2
Correct Option: B

Assume a current flowing as shown.

V2 = 1 × 4 = 4V.

I1 =
4
= 2A
2

I 2 = 2 + 1 = 3 A.
VA = V2 + 3 × 2
= 4 + 6 = 10 V.
I3 =
10
= 5 A
2

I 4 = I3 + I2 = 8A.
V2 = VA + 8 × 2
= 10 + 16 = 26 V.
V2
=
