Wrong. See, for example, Wikipedia.

--- Quote ---If a wire has insulation then the speed is the speed of light in that insulation, say 2c/3 if plastic.

Wrong.

--- Quote ---I have explained on this forum that electricity is mainly due to the flow of electons on the surface of a wire.
--- End quote ---
Wrong. With AC currents there is a skin effect which makes the current density higher on the outside of the conductor than the center. But it is not true that current consists of electrons flowing on the surface of the conductor.

--- Quote ---Electons are photons, that hug the wire. Hence electricity is indeed light, ie photonic.

This is so wrong that I don't even know where to begin.

Believing that you understand physics better than what physicists have figured out in the last 150 years does not make you smart. It doesn't even make you look smart.

This entire topic is a shitshow.

It looks to me that u dont like old electricity, & u dont like my new electricity.
I had a look at wiki for the speed of electricity, & it agreed with what i said, & did not agree with what u said.
Is English your native language?
However i am sure that i could learn something from u re electricity (but it might take a long time).
I am already indebted to u – that wiki link of yours told me that at 60 Hz the speed of em radiation in copper is 3.2 m/s. I have been saying that for DC it is about 10 m/s, & so it appears that my 10 m/s is about right. But i don’t understand how the speed of em radiation is affected by Hz (probably not important today).

But what exactly don’t u like about the topic (Veritasium's gedanken)(energy doesn't flow in wires) of this thread?

If you don't mind reading "old physics" it's here: https://en.wikipedia.org/wiki/Lorentz_oscillator_model
In new age physics, I've no idea  :-X

Is this the wrong time to introduce the G-string transmission line? (Or would there never be a right time?)

Longitudinal surface waves on insulated wire(s), including enamelled. I had to wonder about AlphaPhoenix's experiment at the time.

According to "New Physics", what would the speed of sound be? Is it equal to the wind speed?
