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.

FYI.  In 1965 I got a 1st class honors degree (summa cum laude) in Mathematics, with Physics as a minor.

My dad was a physicist (and a fellow of the Institute of Physics) and my elder brother taught high school students who were going to read physics at University.

Just saying ...

Yep. And you aren't saying anything that is out of kilter with a "moderately up-to-date" understanding of electromagnetism, unlike others on this thread. 😉

@dlevi67

Would you please explain in somewhat laymen terms how a signal travels down a cable.

Thanks

                       WELL: the Cargo Cult's still building runways.

                                          Time for another repost:

Cargo cult science is a pseudoscientific method of research that favors evidence that confirms an assumed hypothesis. In contrast with the scientific method, there is no vigorous effort to disprove or delimit the hypothesis.[1] The term cargo cult science was first used by physicist Richard Feynman during his 1974 commencement address at the California Institute of Technology.[1]

Cargo cults are religious practices that have appeared in many traditional tribal societies in the wake of interaction with technologically advanced cultures.

     Do a bit of research and you'll learn those primitives were limited in their understanding of what they saw with their eyes, based on their prior experience, education and BIASES.

                                                A rewind:

                 It isn't that the Denyin'tologists are ignorant.

               It's they're knowing* so much, that's WRONG.

                       *heart of the Dunning-Kruger Effect

                                              OR, two:

     The Church of the Naysayer Doctrine (like every other faith-based, religious cult) has as many dopes as it does Popes.   

     Bring up anything resembling SCIENCE/PHYSICS, dated later than the 1800’s and they become apoplectic, not having the formal education to comprehend the concepts, or- possible ramifications.    THAT would be hilarious, were it not so pathetic!        

           Gimme That Old Time Religion, Gimme That Old Time Religion, etc.

        At the very first mention of something as simple as Wave Function (a BASIC tenet of Quantum Mechanics), the Cargo Cult will label you a KOOK.

        But remember: they can only view/understand you, based on their limited experience, education and BIASES.

         They have overlooked the fact that, if not for the hypotheses/theories and experimentation, regarding Quantum Mechanics: a plethora of modern conveniences, medical devices and the gear they so love, would not exist.

          Had scientists, chemists and inventors shared the doctrines of the Cargo Cult (Denyin'tologists), there would be no semiconductors, computer chips, LASERs, or Magnetic Resonance Imaging devices (MRIs).

                                         Solid State amps?

                                     OOPS (back to tubes)!

                                        Your Smart Phone?

                                        FA'GET ABOUT IT!

                                         Your car's GPS?

                                                NOPE!

    Then too: some may be willfully ignorant and just enjoy being contentious.

                        Others: obtuse, uneducated*, misinformed?

      *Typically, from what's been exhibited here: H.S. STEM, if that, would be a safe inference.

      Either way: the result, when the Cult begins it's rhetoric, is a classic demo of the Dunning- Kruger Effect.

                                          But, I digress: 

       Bring up those pesky details, regarding the likes of QED, Dielectric Absorption, Poynting's theorem and possible application/effects, relative to frequency, that our musical signals are carried via photon or wave, outside the conductor and you're a KOOK?

         Again: the Cargo Cult can only understand anyone with an actual background, experience and education in Physics/QED, based on their own beliefs, (limited) education, experience and biases.                                      

     One anecdote that some may find interesting; about their walks in the woods and how Richard Feynman's father would encourage him to look beyond the fact that something in nature exists, into why and how.

     It saddened him that while attending college, during a visit home and one of their walks; his dad asked what he was learning in college.

     At that moment he realized: if he tried to explain what he was learning, there was no way his dad could understand.                               

                            It wasn't an insult or condescension.

                                                Just reality.

                                  Oh well: let the cult go build a runway!

           Einstein got that last one wrong (Quantum Entanglement), BUT- I still wish he'd been alive, when the Hubble Telescope proved, what he considered his, "greatest blunder" (his inability to bring symmetry to his field equation, without lambda)

                                            How about that?

Another example of a hypothesis/theory, with no way to EXPERIMENT/MEASURE, what you're sure must be there, in some detectable way, or another.

                                            Happy listening!

My children, who are going through university now, are not taught that, and real images of atoms (electron clouds) are commonplace since the early 2000s. Wake up and smell the roses - you are out of date and out of order.

                                                 HILARIOUS!

        This Dunning-Kruger exemplar doesn't even know the difference, between picturing/modeling an electron cloud and actually viewing an electron.

The cargo cultist is still posting - that is you, @rodman99999

At that moment he realized: if he tried to explain what he was learning, there was no way his dad could understand.

This seems to be the situation indeed. You keep posting things that you don’t understand, and no matter how much I or others try to explain to you that things aren’t how you think they are, you simply cannot understand.#

This Dunning-Kruger exemplar

That would be you, again. Ad hominem does not make you smarter or even seem smarter.

Please - inform yourself before digging yourself further into the solid rock that you have reached 5 posts ago. I will no longer reply to your nonsense posts, here or anywhere else on this forum. Take care.
