How Electricity Actually Works


In November of last year I posted a Vertasium YT vid titled "The Big Misconception About Electricity".  Well it caused quite a stir and like an arachnid had many legs many of which attempted to draw A'gonrs into the poison fangs!

Well, here is the follow-up to that original vid which caused quite a stir in the "intellectual" community as well.

Vertasium "How Electricity Actually Works".

 

This does have implications for our audio cabling...

after following this academic debate, and how/if it matters for audio signal transmission, I am left with some questions.  How does the insulation and multistrand design of most of our cables enter into this discussion?  Secondly, in light of the role of the fields around the wires, does the separation of the two wires ultimately have an effect?  AND FINALLY, though this all may matter for those that design  cables, to the end user, isnt the sound all that matters?

Thank you for posting the links.  

I have only one theory and that is:  As a species we simply don't know a tenth of a percent about anything.

We may know what works and what doesn't but that's about where it ends.  I'm not attempting to be cute or controversial...call it a belief system if you like.

I'm happy that this posting didn't go off the rails like the last one and enjoy reading this thread.

@jw944ts ,

How does the insulation and multistrand design of most of our cables enter into this discussion? 

 

How? Well if I am trying to sell cables that realistically don't sound any different from anyone else, but I want to make it seem like maybe, perhaps it does, then I will bring up insulation, and all kinds of other things that technically have a measurable impact on the wires, but for the purposes of analog audio are completely meaningless so that I can appear differentiated.

 

multistrand design

Flexibility and does improve skin effect but I expect skin effect is not an issue unless you are running a single solid core 18awg, which I don't think anyone is are they?  That was a quick back of envelope estimate for where it may be an issue.

 

Secondly, in light of the role of the fields around the wires, does the separation of the two wires ultimately have an effect?

 

Yes it increases inductance. In any normal construction this is likely to have no audible impact. A poor cable and electrostatic speakers from my limited research may have an issue. I did a quick review of a bunch of speakers impedance plots after my discovery about the high Fidelium resistance.

 

I will raise the issue that for all the marketing claims of cables, the only specifications I could find where inductance, resistance and capacitance. One or two alluded to skin effect, but nothing concrete. No other parameters were provided.

 

 

We as a species don't know a tenth of a percent about anything? Pretty pessimistic view of Homosapiens.
