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.

This article explains and animates what a sinusoidal or sine wave is:

       As did mine (very clearly) and how they're sinusoidal audio/musical signals, in our audio applications.

     As I often mention: there are a plethora of phenomena surrounding us (our universe*), that science/Physics has yet to understan

     For instance: 95-96% percent of what makes it* up, to this day remains unknown/a mystery.

            No one has all the answers, or: can make definitive statements.

      That's why what's studied in our halls of higher learning, is refered to as 'Electrical Theory'.

                                      Regarding entanglement*:

       *That particular phenomenon (second paragraph in above article) has been accepted by Physicists, for decades.

                                            Happy listening!

Were ... the DC voltage/current ... modulated ... into an amplified musical signal; it would appear much more complex, but: still a sinusoidal wave

Your article about sinusoidals did not actually define what they are!  They are pure sine waves.  Musical signals are not a pure sine wave as you stated.  However, any periodic wave can be mathematically represented by an infinite sum of sine waves  each having a wavelength which is an integer fraction of the target wave.

Explanations work best when the terms are used correctly.
