Question

In the circuit shown below, find the transmission parameter C.

(a) 4/5

(b) 3/5

(c) 2/5

(d) 1/5

I had been asked this question in final exam.

I would like to ask this question from Transmission(ABCD) Parameters topic in division Two-Port Networks of Network Theory

Answer 1

The correct choice is (d) 1/5

For explanation I would say: C = I1/V2|I2=0. By open circuiting b-b^‘ we get V2 = 5 I1 => I1/V2 = 1/5. On substituting we get C = I1/V2=1/5 Ω.
