Question

Consider a function Z(s)=5(s+1)(s+4)/(s+3)(s+5). Find the value of L2 after performing the first form of Foster method.

(a) 4/5

(b) 3/5

(c) 2/5

(d) 1/5

The question was posed to me in unit test.

I want to ask this question from Synthesis of R-L Network by the Foster Method in chapter Elements of Realizability and Synthesis of One-Port Networks of Network Theory

Answer 1

Correct choice is (c) 2/5

The explanation: As R2=(5)(L2)

So the value of L2 is 2/5 H.

L2 = 2/5 H.
