Wow! C-H, I knew that if I asked you , you would have SOME explanation! Can you clarify some things:
You said "The wave in an electrical conductor is moving much faster than the electrons" How so? Sorry for my ignorance, but what is a wave, then?
"Superimposing two currents of different frequency will not cause electrons to go in different directions ... at the same time since the cloud follows the resulting total waveform. There will not be two separate waves that propagate via different electrons." You say that that the cloud follows the resulting total wave form. Then how are seperate wave signals sent on existing electrical networks?
