So here is the problem. I don't know why I didn't see this before. You are hung up on the term "alternating current" as if that was an accurate description of the phenomenon. Current in a general sense implies there is a forward motion. If I say there is a current in the river we all know that means the water is flowing downstream. An air current means air is flowing passed some point. Trying to equate that idea to the term alternating electrical current is hopeless since linking the term current and the idea of back and forth is only done in electricity.

The whole debate is stupid. 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. That can be done by various means, for example with wires, waveguides, or through the air. The fact that if using a wire there is a resultant moving about of electrons is really just a side effect. It is not the cause. They are wiggling about because there is an electromagnetic wave passing by. The wiggling about is not causing the wave.

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.

If you had first learned about this as energy being transferred in an EM wave and the subsequent vibration of the electrons you would never have come up with the idea that this was a flow of alternating current. Flow of alternating current just doesn't make much sense, but since we are stuck with the terms we have these stupid debates.

.

You can't give me an example of an alternating flow and use the one we are debating i.e. alternating current. Come up with one that does not involve AC.

As for your defense that it is convention, well, that doesn't mean it is a correct. Textbooks are filled with examples of bad ideas that have taken on a life of their own. Yes, I understand what somebody is trying to describe when they they say flow of AC but that doesn't mean it is an accurate description of what is going on, it is simply an agreed upon convention. Well established precedent doesn't mean it really makes any sense. This is science and poorly worded phrases should be corrected and challenged, not just accepted because that's the way it has always been done.

If you want to describe bathing yourself as "washing up" then I know what you mean, but from a scientific standpoint you did not describe what you were doing any more than flow of alternating current describes what we are talking about.

Sorry, one more thought and I'm done. As far as I can see we've pretty much flogged this to death.

If that makes no sense, then there are countless physics and electronics texts which make no sense as "flow" is commonly used to describe electric current, both DC and AC and has been for over a century.

Yes, that is exactly what I am saying, it literally makes no sense. The English language is filled with phrases that make no sense. Phrases and terminology that if taken literally are quite ridiculous.

You tried to defend the idea that AC current is a flow based on a phrase that has a long history and therefore assumed must be taken literally. You couldn't truly succeed any more than you can convince me that you wash up even though that is a very common phrase.

Take care, feel free to have the last word.

Herman, I didn't quite get your point. Can you explain it another way please?
