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.
I seem to recall that in another post you said you learnt your electricity from this forum?
No, I actually said:
I first learned how electricity works here on Agon in 2010. Oddly the thread was titled "directional cables?".
A member started posting about how an electrical signal actually travels down a wire. I thought what Planet is this guy from?...
Before 2010 I believed, like you, electrons traveled back an forth from the source to the load in a closed circuit. I believed , like you, AC current traveled back an forth from the source to the load in a closed circuit. I believed, like you, the AC signal traveled back an forth from the source to the load in the conductors.
I learned in 2010 what I was taught in K thru12 was wrong how electricity works.... Four years of electrical apprenticeship training I was taught the same wrong crap.
Basically Sefton and Morrison is saying the same thing.
Quote from Ralph Morrison.
If we accept the idea that fields carry energy in space, it must be true at all frequencies. That is the law. If it is true for light, it must also be true for 60Hz power and at DC. For utility power, the energy travels in the space between conductors, not in the conductors. This is not the picture presented by circuit diagrams, where energy seems to be carried by conductors. In digital circuits, the signals and energy travel in the spaces between traces or between traces and conducting surfaces.
Buildings have halls and walls. People move in the halls, not the walls. Circuits have traces and spaces. Signals and energy move in the spaces, not in the traces.
You don't believe any of that.
Your words:
AC or Alternating Current flows for a short period in one direction, then reverses direction repeatedly. Analog audio signals are AC,
I left you this Link below to read. If you would have taken the time to read over it you again would have found you are wrong. You would find the info is the same as Sefton and Morrison.
I think the answer is instantly. The switch is opened, Games over.
This was in response to what happens when a light is switched off, and of course the answer given is so wrong on so many levels!
When the light is on, it is because power is delivered in an electrical circuit featured by voltage and current - likely to be direct current in a car or alternating current in a home. When the current is suddenly interrupted because the switch is thrown, electrical pressure builds up at the switch. This pressure is known as voltage. If the current was big enough, the voltage becomes high enough to ionise the surrounding air and cause sparks at the switch contacts.
This is precisely the phenomenon used by older car ignition systems to generate very high voltages from 12-Volt DC electrical systems.

Context, of my quote, you used in your post above:
Okay, I got a simpler question, what if the load is disconnected before the energy gets there, what happens to that energy?
Can’t happen... The energy travels at near the speed of light. It’s at the light bulb the instant the contact closure completes the circuit... It’s that Fast!
Open the switch you break the voltage feeding the light bulb. Instantly, no light.
If you believe the electrons are moving back and forth in the wire and the electrons are what makes the light bulb light then you might have to wait quite while for the bulb to light up when you flip the switch on....
~ ~ ~
With that out of the way....
Source, 120Vac.
Load, 120V 100W incandescent light bulb.
Simple circuit,
120Vac source, SPST snap switch to disconnect source from load.
Close switch, a completed closed circuit is created.
Instantly EM wave energy flows in one direction >>>, at near the speed of light, from the source and is absorbed by the tungsten filament in the bulb. The energy is not consumed by the filament but rather is converted to to some other form of energy. Therein heat and light.
The event can’t happen unless there is a difference of potential, voltage, applied across both ends of tungsten filament in the bulb. Break the circuit, No longer a difference of potential, voltage, applied to the tungsten filament. Game over! No more light.
(I left out the part of the involvement of current, electric fields, and magnetic fields. All are needed to create the energy electromagnetic wave. Just trying to simplify the process.)
I don’t know what kind of lighting you have in, say, above a bathroom vanity in your home. If The light fixture uses incandescent light bulbs just go to the bathroom flip the wall switch on. Light instantly. Flip the switch off. Light’s gone instantly.
Electricity doesn’t work like water in in a garden hose. Water hose, turn off the faucet and water will continue running out of the hose. Electricity don’t work that way.

As for this:
This is precisely the phenomenon used by older car ignition systems to generate very high voltages from 12-Volt DC electrical systems.
Keeping it simple I’ll use a vehicles back when the electrical system, battery, was 6Vdc.
A high voltage coil is what stepped up 6Vdc to a high voltage for the spark plugs.I can’t remember how many thousands of volts it was back then.
The coil was, to me, a step up autotransformer. IF 6VDC was directly connected to the 6V pos and neg terminals on the coil it would work like an inductor. Not a transformer. A transformer only works when connected to an AC source. OR a pulsating DC voltage. So if you took the battery lead that feeds the neg terminal on the coil and momentarily touched it to the neg terminal on the coil, (completing the circuit), then remove the lead, (breaking the circuit) a high voltage would be induced on the high voltage winding. Electromagnet induction...
And that is the basics of how it works.
Of course for the ignition system of the vehicle there is a lot more to it. The thing that’s used to pulsate, make - and - break the 6Vdc to the coil primary winding is a spring loaded open and close set of "Points", contacts. A Condenser is wired across the set of contacts to extend the life of the contacts. There is a shaft on the distributor that is mechanically driven by the engine camshaft. It’s all about Timing! The distributor shaft has lobs on it that open and close the Points. There is a lot more to what goes on, but I’ll stop here...
@rodman99999What would the high voltage output of the coil look like on a engine diagnostic scope? Example... A choppy, say, the top half of an AC sine wave? Never really thought about it...
The voltage on those coils was in the 20-40K range, and everything was DC (6,12 or 24V).
DC voltage on an O-scope will just appear as a straight, horizontal line and read consistant with the scope’s voltage demarcations/setting.
On an engine analyzer: everythings zero, until the magnetic field in the coil collapses and the resultant high voltage is sent through the distributor, to a plug.
At that point: there’s a pronounced spike on the screen, repeated every time the points open and which appears very similar to an ECG trace, without the secondary pulse (lub sans dub).
But quantum entanglement has no practical applicability to music reproduction today.
Who said it did?
I pointed out: the phenomenon of information being instantaniously transmitted between entangled particles, has been accepted by Physicists, for decades.
ie: Even Einstein recognized the phenomenon, referrring to it as, "spooky action at a distance", 80 years ago.
I could have as easily used the phenomenon of a Bumblebee's ability to fly and that being accepted without explanation by the World's best Aeronautical and/or Aerospace Engineers, until Fluid Dynamics was developed. Only then could Dickinson use that science, to model how it could lift that fat butt into the air, with those tiny wings (circa 2005).
Another example might be why humans can smell/differentiate a vast multitude of odors*, with only something like 400 nasal receptors.
*some say 10K, some: a trillion.
21st Century experimentation in Quantum science says it's likely that our noses are actually listening to and recognizing the frequencies/sounds, generated by atoms and molecules, via quantum tunneling.
Okay, I was kinda done with this thread, but in response to this:
Can’t happen... The energy travels at near the speed of light. It’s at the light bulb the instant the contact closure completes the circuit... It’s that Fast!
Ponder this: You are watching a particular star on a clear night with your telescope, and suddenly you don’t see it anymore, you keep looking, perhaps it was blocked by a plane or some other object, or bent by some other huge object in a distant galaxy, but then after some length of time you are convinced that it must no longer be there, and how cool is that! You just witnessed a star burning out! You witnessed a star that had been burning for perhaps billions of years suddenly die! But in fact it "burned out" thousands of years before you were born- it just took that long for that last bit of light to reach your eyes.
