Sinusoidal Circuit Analysis (No Lab)

Today we went over the circuit analysis methods that we used to solve DC circuits. Here is a list of all the methods.

The above methods still work in AC circuits as they work in DC circuits. Here are some examples of what we did in class.

Nodal Analysis

Mesh Analysis

Superposition

Source Transformation

Summary: Notice that superposition method is the only one that works for sources of different frequencies. When we turn off and on a different source, the impedances of capacitors and inductors have to be recalculated since they are frequency-dependent. All the other methods still work in AC circuits as long as frequency stays constant.
