I really like the Fundamentals videos and this one is no exception.
Is there a 'Fundamentals playlist' somewhere? Wouldn't it be cool if the playlist was in the same order as a Uni course in DC circuits. Ohm's Law, Thevenin, Norton, Kirchhoff, ... (as I recall from about 50 years ago...)
Then I would want AC Circuits, active circuits and so on. Essentially a 4 year program. for the cost of bandwidth.
