Bill Lowe of AudioQuest is another that says solid core wire is directional. Lowe was saying it back in the 1990s....

I assume you are still using the older Cardas ics.... The arrows point away from the source.
Even though there is no audible difference, I usually recommend that customers hook up the cables so that the signal flows the same direction as the printing. - BrianWhy do you suppose that is? Could it be the way the wire conductor came off the spool?
I suggest you try the ics both ways. just make sure the direction of both cables is the same, arrows or printing...
.... The arrows point in the direction the signal is flowing. If there are no arrows the writing on the cable follows the direction of the signal.
You can't just throw out a blanket statement like that.
Older Nordost Blue Heaven ic cables, the arrows pointed to the source.
If memory serves me right an early ic cable of Ray Kimber's made for the CDP to preamp, the arrows pointed to the source.
Here is what Audioquest was saying in the 90s.
Fact: All cables are directional, from hardware store electrical cable to the finest pure silver cables. Some cables should be used with the writing going in the same direction as the music (toward the speakers), some should be used in the opposite direction. If you are missing the instructions as to which way to orient your cables, check with your dealer (Audioquest puts instructions on every spool of cable). If necessary you can determine which direction is best yourself, simply listen to the cables in one direction and then the other. The difference will be clear, in the correct direction the music is more relaxed, pleasant and believable. While cable directionality is not fully understood, it is clear that the molecular structure of drawn metal is unsymmetrical, which does provide a physical explanation for the existence of directionality.
Here is the instruction from a box for the Lapis cables.
Ah. I didn't know users could edit or delete their posts.
You sure can.... You only need to log in..... Then at the bottom of your post you are given the option to edit or delete the post.
Just click on (edit my post)
Now you can only edit your post until someone else posts a response....
Or after so many posts have been posted to the thread.... I believe 50, can't remember for sure.
So for a typical AC current in a typical lamp cord, the electrons don't actually "flow," instead they vibrate back and forth by about a hundred-thousandth of an inch.
Does the charge alternate back and forth? Is the charge current?
If a scope is connected across a 120Vac 60Hz difference of potential we see a sine wave. Exactly what are we looking at? (I realize the scope is looking at the 120Vac 60Hz source but can we see the scope as a connected load by 2 wires for discussion purposes.)
For one cycle:
We see two halves of a cycle? Starting at zero swinging positive then back to zero then swinging negitive back to zero.
One positive wave form followed by one negitive wave form.
Or visa versa.
The ampere (symbol: A) is the SI unit of electric current and is one of the seven SI base units. It is named after André-Marie Ampère (17751836), French mathematician and physicist, considered the father of electrodynamics. In practice, its name is often shortened to amp.
In practical terms, the ampere is a measure of the amount of electric charge passing a point per unit time. Around 6.241 × 1018 electrons passing a given point each second constitutes one ampere.
If you want to describe this wiggling about, this vibration of electrons, this back and forth motion as flow then go right ahead. You are probably the only one doing so but why should it matter to me. The real flow that should be discussed is the flow of that wave.
No Simply_q is not the only one... More than likely all the Electricians and Linemen around the world call it current flow. ANSI, IEEE, NEC, UL, CSA, call it current flow.
Fuses are rated in amps.
Motor data plates give the FLA (Full Load Amps) of a motor.
Clamp an Amprobe around a current carrying conductor, it measures the flow of AC current in amps...
Whoever started using the term alternating current to describe what we are talking about was an idiot. The only thing that is really important here is the movement of the electromagnetic wave from source to load.And from the load back to the source. A closed circuit, current flow...
Ohms Law... E = I x R.... If we know E and we know R then we can find I. I? How much current is flowing in a closed circuit.
The movement of the EM wave is not current. The energy in the wave is absorbed by the load and converted into some other form of energy such as heat or light or if the load is an antenna it is radiated off into space. It does not flow back to the source.
Have you heard the saying,.... current flow, amps, is the same in all parts of a series circuit.
If there is no current flow why does the flash light battery go dead if the switch is left on?
Current will flow through the filament of the bulb until all the power of the battery is exhausted.
Jea, yes, the charge is vibrating back and forth with the electrons.
Does the charge change state as it vibrates back and forth?
+ - + - and so forth?
I assume if the frequency is 60 Hz the charge changes state 120 times per second, one cycle.
Base line 0 + 0 - 0, one cycle.
If electric current is the movement of charge what is wrong with using the word current in place of the word charge?
With the load consuming power from the supplying alternating voltage source explain the process movement of current to the load.
So it isn't + 0 - 0 + 0 - as in the charges are changing polarity it is L 0 R 0 L 0 as in the negative charges are vibrating left and right around a zero point.So if I understand you correctly even though the generator is putting out alternating voltage, where the voltage changes polarity, all a connected load sees is pulses.
L 0 R 0 L 0 as in the negative charges are vibrating left and right around a zero point.
Why does the scope show a sine wave with a positive amplitude and a negitive amplitude with a peak to peak voltage or RMS voltage?
I am apparently missing something here.....
With the load consuming power from the supplying alternating voltage source explain the process movement of current to the load.Herman,
It seems I misspoke and used the word "to" instead of "through". As we both know current is the same in all parts of a series circuit.
As for the use of the word "power" being consumed instead of "energy",... Well in my mind I guess they were the same.
In my defense on the back of a lot of equipment one sees power consumption of so many VA or watts. I have not seen energy consumption best that I can remember. On audio equipment anyway.
Here is some reading material for you to read:
Who is Herman?
