Day 20 - Sinusoids and Phasor Cont.

Topics Discussed

On day 20 of the ENGR 44 course, we further discussed sinusoids and phasors, integrating previous circuit analysis methods into these AC circuits.Interestingly, having an understanding of how to work in the complex domain of numbers makes these methods relatively simple. We focused on using nodal analysis, but also were introduced to mesh analysis as well. (Fig. 1)

We did a few problems that focused on mesh analysis (Fig. 2). We did no lab since the lab for this day was the same as the previous.

Summary

Although there was no lab to get actual hands-on learning, we were able to apply some old skills to new problems and thus develop a better understanding of how to analyze AC circuits.
