Electric Circuits 101

Faced with an insurmountable amount of free time during the Corona Virus outbreak, I found myself rereading old undergraduate textbooks, and in turn, toying with the idea of challenging myself with the task of teaching the content. What resulted from that can be found below:

Various Tricks

In my first year Mathematics class our lecturer would always refer to the "various tricks" we would employ. Here are some of the ones I struggled to grabble to most, or the ones I found most interesting.
