Edit:
It is good now.

It was public an hour or so ago.

Why not do some spice models and test them

Reminds me of when I did an internship in a government agency.

I was redirected to their electronic & instrumentation division, my mentor presumably is an 'expert' on this field and given a task for me to build what I know now as bench PSU with CV CC capability. He explained hell lot, it overwhelmed my still innocent uni student brain. It didn't make a lot of sense what he was explaining, about the circuit has to be sourcing constant in voltage AND in current........... I got back to him how does that make sense if the Ohms Law math doesn't even add up? And what happens if you unplug the port where does the current go? He just said that the Ohms Law doesn't apply in this application.

I never felt so betrayed that I was unable to complete this task, mostly my fault because I was so dumb.  |O

By the way we don't spell the 'h' in Thévenin. It's like Tévenin :)

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.

GIven that I am kinda following a complete DC/AC learning path here, I have thought about maybe a page on my website that lists them all in order.

That would be outstanding!  It would really help newcomers learn the material in a traditional sequence.

Wikipedia has a rendering of the original paper, "EXTENSION DE LA LOI D'OHM" and he (or the publisher) spelt (not spelled) his name with a "h". When I worked in France a while back, I tried to use the word "malcontent" and was told that word hadn't been used for several hundred years  :(  I got a more positive reaction with the description of our common enemy: perfidious albion.
