Guys;

That's the difference between "electron flow" (which flows from the positive treminal to the negative) and "hole flow" which flows in the opposite direction...both had eras when their teaching was favoured...it does make for problems when those who were taugh in different eras get together without clarifying...but when it comes down to it, what's the difference which one you learned...as long as you understand that when there is a voltage difference, current flows, and as long as you don't "change horses mid stream" as they say.

I happened to have learned that "holes" (or the absence of electrons) flow from the negative terminal of the battery to the positive terminal...whatever...

Cheers
