I think that Thévenin needs to be very well-known, and it's not
difficult to understand. By the age of 12 I knew Ohm's Law, but I
couldn't understand 'internal resistance', because it seemed to be
something different from ordinary resistance. If someone had explained
Thévenin, I think I would have made a lot quicker progress in
understanding electronics. It was a real 'road-block' for me.
It's a pity that Monsieur Thévenin wasn't 'Monsieur Dupont'. Less exotic
