Question 1

Network Theorys-Domain Circuits

The Laplace-domain impedance of an initially relaxed inductor is?

Show AnswerHide Answer Report an error

Correct Answer: B. sL

Explanation: With zero initial current, V(s)=sL I(s), so the inductor impedance is ZL(s)=sL.

Reference: Standard network theory: inductor s-domain impedance

Correct Answer: B. 1/(sC)

Explanation: With zero initial voltage, I(s)=sC V(s), hence ZC(s)=V/I=1/(sC).
