Hi Bob !

Are you sure those damn electrons  "flows" as you want to ?
And are not using some clever ways to fly, for example just jumping
( teleportation ? cuantum effect ? ) from
the A to the Z end of one wire, without passing by all B, C, D...etc
intermediate points ? Just take a deep thought in a spare programming
time. And please do a connection between this ideea and the tunneling
effect and the microwave generation, ( and why not, the skin effect ).
 Then you'll
never say again: "electrons flows ( like the water) from - to +"
and of course not like "conventional current" either.

I'm very carefull when I'm explaining such things to any 10 years old
child, because all classical explanation are just formal. And that child
will remeber all his life a wrong explanation.
And the students from this list, too...


best regards,
Vasile
