[Amps] Zener Screen Regulators

[Al Kozakiewicz]

If a negative charge flows left, then a positive charge appears to flow right.  Yes, only the electron "physically" moves.

As I said, it's an arbitrary engineering convention, most likely born from the fact that electronic equipment from the earliest days (except 1950's British sports cars!) ground the negative of the power supply.

REPLY: 
I agree, but there are no positive charges which flow. Only negatively charged electrons flow. 

Ben Franklin made the original mistake long before anyone knew about electrons.
By pure 50-50 chance, he got it wrong.

Why is this so hard to understand? Even more curious, why not fix it?
