Day 7 of Linear Circuits. We introduce how circuits with multiple voltage sources and/or multiple current sources can be simplified. It turns out, that this is very straightforward based upon our earlier lessons: 1) Voltage sources only have one job (Vpositive = Vnegative + Vsupply), and 2) Current sources only have one job (Iwire = Isupply).

The material covers all of the lecture material from a seventh lecture in a traditional, sophomore-level linear circuits class.
