How Electricity Actually Works

This does have implications for our audio cabling...

I haven't seen anyone explain how...does it have any implication for wireless speakers? 

@rodman99999 
I managed to get through the first page of the discussion you referenced and there had already been two pleas to steer it off to a siding. I noted that ‘This discussion is closed’ sign. I don’t believe that discussion had anywhere to go, like you say; I had hopes for this one. 

@czarivey

Current doesn’t carry the signal. The electric charge moves too slow... As slow as cold Maple Syrup. Electrons don’t carry the signal either. They pretty much vibrate in place and hardly move at all. And the signal definitely does not flow back in forth from the source to the load. The signal travels is one direction from the source to the load in the form of an electromagnet wave in the space between the conductors at near the speed of of light in a vacuum.

As for Ralph Morrison you obviously don’t understand what he is saying.

It is also obvious you didn’t read the other link I provided for you to read.

I skimmed it. What were you questioning?

@deludedaudiophile

I wasn’t questioning anything the educator had to say. I just wanted to see if you agreed....

@jea48 ,

I just skimmed. It all appears to be classical electrodynamics so nothing seemed out of order. I thought the way he approached the argument, i.e. arguing what is wrong with electrons moving was both effective, but at times convoluted due to the wording.

The problem in discussions like this and the audience is misuse and misunderstanding. The moving charges (electrons in this case) are still required for the magnetic field. There is more complexity than most of the energy is outside the wire. But even though most of the energy is outside the wire, does not mean for the use case, audio, specifically analog, that fancy dielectrics, special geometries, and other claimed design features are relevant. To be relevant, they need to be quantified, and then compared to the signal. A critical parameter is wavelength/distance. When this is a very large number, then connection systems can be modelled with simple parameters such as R,L, and C and related to C, dielectric absorption, though in most cases, low source or load impedances would make this irrelevant. Going up in frequency, skin effect is the next likely to be relevant. Shielding is relevant, but there is well understood practices to limit the effects of external fields.
