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

  • A1/(sL)
  • BsL
  • CL/s
  • Ds/L
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
