directional cables?

when you posted "I'm afraid that's incorrect. Current flow is indeed a flow of electrons. Electrons ARE the charge carriers, which is why we call this field "electronics" instead of "protonics." in response to

Nsgarch - electric current is a flow of charge and not a flow of electrons. Electrons move very slow - at about 0.1mm/s (drift velocity)

I took that to mean you disagreed that current was the flow of charges since I don't see any other way to read that statement. If that is not what you meant then I apologize.

Herman, Did I read that right? Did you really say you apologize?

I don't see how you could have taken it that way.

The original poster claimed that current was the flow of charge, not electrons. I said that was incorrect, that current was indeed the flow of electrons and reminded him that electrons were the charge carriers. In other words, in the context here, electrons and charge were one and the same.

If that is not what you meant then I apologize.

No problem.

By the way, what happened to the rest of your post? When I read it the fist time, I recall your saying something about positive charge carriers in materials other than metals.

Once again - Electric current is a flow of charge ALONE. At 1kHz electrons are practically standing still (vibrating +/-0.0001mm) NEVER MOVING ALONG THE CABLE while charge is reaching destination with almost speed of light (0.6-0.7).
Electrons might be carriers and you can calculate numbers from amperage but they don't "Flow" - charge does.

Herman - for that reason never apply DC to expensive audio cable or you will slowly loose good electrons you paid for (just kidding).

Mr Simple, I decided the stuff in my last post about positive charges really didn't relate to your response so I deleted it.

I see what you mean but by defintion current is not the flow of electrons, it is the flow of charge. Since we're talking about cables then electrons are indeed moving about but you don't have to have moving electrons to have electric current since it is sometimes positive charges.
Refer to this http://en.wikipedia.org/wiki/Electric_current

Since the flow of charged electrons is relatively easy to envision it is used a lot, an analogy to water is often used even though it breaks down if you try to apply to all electrical phenomna. To truly understand what is happening you need to move beyond the electron model and think in terms of energy, in terms of electromagnetic waves, in terms of things where the math gets so complicated most people including me can't understand it well enough to even know what it is they are missing. However, I do know enough to understand that electron flow can't explain everything happening in electronics.

Rrog, yes, why would that suprise you? If I am wrong I am willing to admit it, unlike others around here. However, after reading Mr Simple's response I think I may have been correct since he is indeed equating flowing electrons with flowing charge,
