Question

What is the Thevenin equivalent transform impedance at terminals a-a' for the circuit (see attachment) ?

Answer 1

Here are the possible answers for the exercise.

Answer 2

Answer (1)

Answer 3

\[Z(s) = [L.s(R+1/(C.s))]/[L.s+R+1/(C.s)]\]
Remplace L,C,R by value and plays with the factor 's' to get the right answer (1).

Answer 4

Thank you for your time,that was very professional.
