As I slowly move my way through all of my EE classes, I keep running into things that seem to come out of left field. The first one was the unit "nepers per second", which apparently is just another way of saying "radians per second." I swear someone makes this stuff up just to torture undergrads.
The latest, though, is the dot convention on magnetically-coupled coils, aka transformers (including autotransformers). Can someone please explain to me what in the physical construction of a transformer creates this weird kind of independent polarity on each coil? I don't remember ever encountering this before.
