[Amps] Zener Screen Regulators

[Al Kozakiewicz]

By definition, current flow is the flow of charges.  The fact that negative charges are embodied by a particle (an electron) is interesting, but irrelevant.

Negative charges flow in one direction; positive in another.  The use of the direction of positive charges as the direction of positive current flow is entirely arbitrary.  But it is the convention and is every bit as valid as the inverse.

REPLY: 
One of life's great mysteries to me is why the professional electronics community continues to propagate the falsehood of "conventional" current flow.
It is as if civil engineers designed things based on water that flows uphill. 

Perhaps in the next life the creator can explain it to me. No one in this life ever has.  :-)
