In just which direction does electricity flow anyway?
In the 1700s, Ben Franklin arbitrarily defined charge:
Positive on glass rubbed with silk & Negative on rubber with Kitteeee.
Booms first Physics text used + to - and Right Hand Rules.
Then came the Edison Effect and Vacuum Tube Electronics. Electron flow is electric current.
In the early 20th Century, Thermionic Emission showed that its - to + and Left Hand Rules. The Texts were changed.
In the 1970s, we have Solid State Electronics, the transistor and computer chips. Its now possible to have two current carriers-- Electrons (negative) and Holes (positive carriers).
Computer Engineers blew it. They used the Hole Flow definition and they defined the symbols for solid state devices with current flowing from + to -.
So to conform to their symbolism, new texts are reverting back, to the WRONG definition of current flow in a wire. + to -.
Ill ask you this:
What would you think if I told you that the earth is flat?
If I taught you that things roll uphill? (The Mystery Spot).
If I said that the San Lorenzo River flows from North to South, but its current flows South to North?
Well, thats what these people are saying, electrons flow from - to + but the current flows from + to -. They call it
Conventional Current Flow.
Is there any hope!
