Question

Consider the admittance function, Y(s)=((2s^2+16s+30))/(s^2+6s+8). Determine the value of L2 after performing the second form of Foster method.

(a) 4

(b) 1

(c) 2

(d) 3

The question was asked in an international level competition.

I'm obligated to ask this question of Synthesis of R-L Network by the Foster Method in section Elements of Realizability and Synthesis of One-Port Networks of Network Theory

Answer 1

Right option is (b) 1

The best I can explain: We got P2 = 1

And L2=1/P2

So the value of L2 is 1H.

L2 = 1H.
