[Amps] Electron HOLE flow

[Paul Elliott]

Everyone is free to use whatever nomenclature he or she wants, but
communication is easier when everybody uses the same nomenclature.  

Currents exist in places other than wires or inside vacuum tubes.


 

Way back in the dark ages when I was in school, I was taught:

 

1.	Current does not "flow".  Charge flows.  Current was the word used
for flow of charge.  A professor, whether EE or physics, would crucify any
student who used the words "current flows".

 

2.	Transferring one positive coulomb from Point A to point B produces
the same potential difference of  Point A with respect to Point B as
transferring one negative coulomb from point B to point A.

 

3.	In an electrolyte whichever direction a free electron or
negative ion is going, a positive ion will be going in the opposite
direction.  Both contribute to the current.

 

Vacuum tubes can be damaged by bombardment of filaments or cathodes by
positive ions, which are moving in the direction opposite to that of the
free electrons.
