Lets see;
When I learned my electronics, we were taught that electrons migrate from atom to atom toward a point that was deficient of electrons (+ ions) = atoms wanting/requiring electrons to become stable (equal number of protons and electrons).
And vice versa, wanting to depart from (- ions) atoms that have an over abundance of extra electrons, requiring to get rid of the extra electrons to achieve stability.
Thus, electron flow is from negative (-), toward Positive (+).
And, I can understand the opposite concept referring to "Hole" flow.
However, I see more and more these days where folks demonstrating current flow show current flowing from (+) down to (-) (gnd). Did I miss something ?
I was watching TV the other day and there was a demo of electro-plating a chrome vehicle wheel.
They showed emmersing the wheel and the bar of (whatever the material is) into solution and had the wheel connected to the (-) and the bar connected to the (+), and, showed that the bar material would diffuse through the solution and attach to the wheel, thus chrome plating the wheel.
I thought, that's not right, they'll coat the bar with the steel of the wheel, etc.
Then in a couple of other instances I see where folks show current flow from positive to negative. That just throws me off, who is responsible for teaching this absolute opposite theory to the world these days??
Maybe I'm mistaking "current path" with "current direction", but still, if they have an arrow on the end of the line that shows me "direction of flow, etc..
Just thought I'd ask about this......
