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?
