We started the class with an opener on MESH ANALYSIS. And Mason saw that it was good.
We talked a bit about transistors and how they're equivalent to a voltage dependent current source from collector to emitter and a voltage source from base to emitter (NPN). Technically, the voltage source is a diode, but hush now Thor, soften your thoughts into simplicity, and spread not the dangerous knowledge of diodes. There we go. Voltage source. 0.7V.
Onto greater enemies: Lab Mesh Analysis 2 will be a worthy adversary!
Interestingly, the mesh analysis labs are named "Mesh Analysis", "Mesh Analysis 2", and "Mesh Analysis III". Were there a fourth edition, I might dub it "Mesh Analysis Four" to keep to the naming pattern.
Look there! Notes and Matrices!
1. Schematic, estimates for v1,v2
So this is the set of calculations that led me to the apex of my assault on Mesh Castle. See the assault below:
2. Measuring resistance values and circuit testing
3. Measured values and error
We think we had a pretty good set up with low (enough) error. There may have been some discrepancy between the resistances used, leading to a higher than expected current. But all in all, we're fairly satisfied with our subjugation of Mesh Castle.
Summary
Mesh currents make for simple enough equations when Nodal analysis seems to have gone to crap. This is a useful thing. Transistors are some weird little dudes that limit current based on voltage on their base pin. They're good for modulating current, kindof like a switch. But not really.
I'd lastly like to point out that Alex wrote a funny sentence (both haha funny and that's not how a sentence works funny) that I'd like to wrap up with here: "Overall, our lab successfully verified the usefulness of mesh analysis." He's a funny guy that Alex. Don't tell him, but he should shave that waxed carpet that's moved in on his upper lip.
