Lecture (L7-9) Phasor Domain Analysis Techniques

Introduction:  All of your favorite circuit analysis techniques (node voltage, KVL/KCL,etc.) work with impedances too!  ALL methods you learned previously for analyzing resistive (R) circuits apply the SAME way to RLC circuits using impedance (Z) instead of resistance (R).  Impedance: ZR = R ;  ZC = 1/(j$\omega$ωC); ZL = j$\omega$ωL ; $\omega$ω = 2F; j = sqrt(-1)
