Text ## Lecture (L7-9) Phasor Domain Analysis Techniques
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).
Application of the Day: Noise-Cancelling Headphones (Tech Brief 22) Links to an external site.
Questions of the Day (Learning Objectives)
How do you analyze circuits in the phasor domain? ... For circuits with any combination of AC (sine wave) voltage and current sources, resistors, and capacitors, how do you find the voltages and currents using KVL/KCL or node voltage?

ALL methods you learned previously for analyzing resistive (R) circuits apply the SAME way to RLC circuits using impedance (Z) instead of resistance (R). Techniques we have learned include:
- Equivalent resistance --> Z in series and parallel
- Voltage and Current Dividers
- Thevenin/Norton (Source transformation)
- Superposition
- Mesh Current
