Directional wires/cables

Is there any reason to support the idea that cables, interconnects or any other kind of wiring can be considered directional? It seems that the theory is that carrying current will alter the molecular structure of the wire. I can't find anything that supports this other than in the case of extreme temperature variation. Cryo seems to be a common treatment for wire nowadays. Extreme heat would do something as well, just nothing favorable. No idea if cryo treatment works but who knows. Back to the question, can using the wires in one direction or another actually affect it's performance? Thanks for any thoughts. I do abide by the arrows when I have them. I "mostly" follow directions but I have pondered over this one every time I hook up  a pair.

Derek discusses the case of a very simple circuit (a battery, a switch and a 'load' which could be a lightbulb), but it's easy to see how the exact same physical mechanisms are acting on a complex, variable signal ('music'), and why lumped element models are used to simplify the representation... to the point where they can over-simplify it!

         Derek discusses DC, while our conversation hinges around AC*, whether in our power cables, or- signal wires, which carry waveforms (either 50/60Hz or musical), the propagation speed(s) of which, depends on factors like frequency(s) and dielectric absorption of the dielectric involved.

                       *Mentioned before my first link, in my first post.

Do you even understand what response to impulse is, or how this is relevant to any and all signals? Very clearly not. Kindly stop posting things that do not have any connection to physics, history or reality, but only to your totally incorrect understanding of them.

 The story you keep telling yourself that ’nobody understands electricity’ is completely false - and funnily enough, it was Feynman that with QED (Nobel in 1965) added the last pieces to the puzzle. You quote, but you don’t read or understand.

       To anyone ACTUALLY INTERESTED in expanding their understanding of this idea/theory, as regards electricity/electromagnetism, I repost:

      There are simply too many variables and unknowns (95-96%) in our universe, that disallow the categorical propositions, presented by the ignorant/uneducated.

Sorry, but this forum is open to all, even to those like you who claim to be a "victim" of the conversation here.

I'm glad to know I'm not the only victim
