Lesson 16 — Complex Math and Impedance#
Rectangular and phasor form, the sinusoid-to-phasor transform, impedance, and why every Block 1 tool still works.
Objectives covered
2.3 — I can model capacitors and inductors as complex resistors and use circuit analysis tools (such as voltage dividers, Ohm’s Law, and the power equation) to calculate voltage, current, and power in AC circuits containing these components.
