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.

What about ones that do not have directionality in mind? Will they "learn" to be better in one direction than the other? This would mean that they physically changed over time.

No, they won't - there is no "direction" to an AC signal that would change the material to conduct preferentially in one sense rather than the other - and if there were, it would be a cause of significant distortion. Either the cable is manufactured asymmetrically (with different shielding or cable geometry) or it isn't - the asymmetry may cause differences in sound when the cable is plugged in one way rather than the other, but the asymmetry would not change because a signal is sent (from a human "teleological" perspective) from A to B instead of from B to A.

             Inescapable FACT: No one understands exactly how electricity works.     

                         That’s why there’s so much Electrical THEORY.     

        The number of Wiki-Scientists on these pages, attempting to win the IG-Nobel Prize in Pseudo-Physics, is always amusing.             

       Whenever some highly educated person actually does discover exactly how electricity functions, they’ll be lauded by the scientific community, will have solved some of the disparities between Relativity and Quantum Mechanics, receive a Nobel and we’ll hear about it.     

      Newton’s THEORIES were largely superseded by Einstein and Bohr's.   Then came Feynman’s.       For now; none of you can absolutely prove your statements (theories), regarding electricity, FUSES, wires, or anything else, as regards our systems.    

             The following articles, read in sequence, illustrate my point:

     When the steam locomotive came on the scene; the best (scientific) minds proclaimed, "The human body cannot survive speeds in excess of 35MPH."

      Until recently (21st Century); and the advent of the relatively new science of Fluid Dynamics, the best (scientific) minds involved in Aerodynamics, could not fathom how a bumblebee stays aloft. 

     Often; Science has to catch up with the facts/phenomena of Nature and/or, "reality" (our universe). 

     I haven't been in school since the 60's, but- at Case Institute of Technology; the Physics Prof always emphasized what we were studying was, "Electrical THEORY."  He strongly made a point of the fact that no one had yet actually observed electrons (how they behave on the quantum level) and that only some things can really be called, "LAWS." (ie: Ohm, Kirchoff, Faraday)   

                         PERHAPS: that's changed in recent years and I missed it?

Before continuing, kindly get a degree in electrical engineering ...
