Lecture (L7-4) Phasor Domain Analysis (KVL/KCL) & Impedance Transformation

  • Due Apr 1, 2019 by 9:40am
  • Points None
Question of the Day (turn in before class)
  • What is Impedance?
  • What are the impedances of R,L,C elements?
  • How can you analyze the voltage and/or current in RLC circuits using:
    • ohms law?  (see example that starts on page 358) 
    • voltage and current dividers?
  • How can you combine impedances in series and parallel?

Introduction:  R,L,C circuits can be analyzed by converting L and C to impedances and treating them like complex resistances.
