Question

Determine the value of k in the circuit shown below.

(a) √LC

(b) √((L/C))

(c) √((C/L))

(d) √((1/CL))

The question was posed to me in exam.

I'd like to ask this question from Constant-K Low Pass Filter in chapter Filters and Attenuators of Network Theory

Answer 1

The correct answer is (b) √((L/C))

Easy explanation: We got Z1Z2 = L/C. And we know Z1Z2= k^2. So k^2 = L/C. So the value of k is √(L/C).
