This "Electrical theory 1" class instruction is very much in the "only kinda sorta accurate" category.
By which I mean, about every other statement isn't actually true.
The instructor doesn't seem to know much physics beyond the level of what's on the slides and is clearly bullshitting when asked questions about why stuff is the way it is. A student will ask "is that because of <other concept>" and he'll nod and say yes even when they're not actually very related.
Knowing the material better than the instructor is really uncomfortable :/
Re: the pictured sides: I was really tempted to ask "so why is copper more conductive than potassium?", but that would have been kinda mean and entirely unproductive.
@starkatt even better, ask for details on Cooper pairs
@Felthry I confess, I had to look that up.
