5/18 No Lab. Sinusoidal Circuit Analysis

Today, we had no lab, but we did Sinusoidal Steady State Analysis.
Here are the steps to analyze AC Circuits:
1. Transform the circuit to the phasor or frequency domain.
2. Solve the problem using circuit techniques (nodal analysis, mesh analysis, superposition, etc.).
3. Transform the resulting phasor to the time domain.

Basically, it is just what we did before, but with complex number.

The picture above is an example of using nodal analysis in AC circuit.

The picture above is an example of using mesh analysis in AC circuit.

Summary

We learned how to analyze AC circuit by using what we learned before, like nodal analysis, mesh analysis, superposition theorem, source transformation, and Thevenin’s and Norton’s theorems. Nothing new.
