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.

                         Still working on those paragraph/typing skills.

     In the Feynman/QED model: the electron oscillates and generates a virtual photon/particle.

                  Someone mentioned liking to hurt their head?

       Dielectric polarization also comes up in the discussion, toward the conclusion and Feyman diagrams.

@rodman99999,

Would I be wrong saying nothing, life, would exist without EM waves?

I ran across this video years ago which, to me, says life would not exist.

Electromagnetic waves and the electromagnetic spectrum

(To watch the video X out of the blue box by clicking on the white X upper right hand side of blue box. Then press start.)

Audio frequencies would be to the far left of the electromagnetic spectrum. My understanding because of the audio frequencies EM wavelengths wires are required to guide the EM waves from the source to the load.

What say you?

And or herman?

     From a cursory reading, seems that link mostly deals with the need for the EM spectrum, regarding things around us and whether we could do without it.

                                  How about, "living" without:

                                                      and/or:

                                                          ?

     I will admit: it often appears many seem to exist, without the first (ie: Alpha, at least entirely/correctly) functional.

                                               Happy listening!

jea48 -

     Regarding the vid in that link: replace, "change" with, "disturbance" and you have the same basic descriptions/principles as my link on virtual particles.  Insert, "oscillation" for either and you have the description I use most often.

     The pictoral representations and nomenclature/semanics, contained in the various, previous postings/links, on our model/theory (QED) may vary greatly, but: all represent the same basic particle/wave functions and the Right-Hand Rule.
