You just sit at home and make this stuff up don't you?
Drum roll ... it does not matter how fast the electrons move ... they all move at once. It like a water hose or pope that is already full of water. When you turn on the tap, you don't have to wait several seconds for the water to come out, it comes out near instantly (well function of the speed of the pressure wave .. note how I use actual technical terms that are associated with the effect).
The speed is about 2/3 the speed of light.Â
Again, quite obviously you are reading things you don't understand, mixing up what things mean, then misapplying it to other things.
The thing that travels near the speed of light is the electromagnetic wave.
I am not sure you understand what a photon is. Electrons emit photons when they transit from a high energy level to a low energy level, but that is not what the "signal" is. Are you now confusing transmission in copper with lasers? ... or are did you read a Feyman text but not understand it was an analogy, not an actual description of what occurred? Â Electrons could emit photons in a wire (and would), but that is not how current flows.Â
This is just so whacky I am not sure if you are trolling at this point. You can't really be this off -base can you? It's silly.
The electrons are not the signal ... the electromagnetic wave is, but that electromagnetic wave uses electrons (effectively) as the carrier for that wave and sweeps them along, not at the wave speed, no more than air needs to move at the speed of sound to transmit sound.Â
It takes 1 hour at a current density of about 10 amps/mm^2 in copper near room temperature ... yes I do.
geoffkait17,590 posts10-21-2019 5:17pmThe measured difference in voltage drop is a symptom or hint that wire is directional. The lowest voltage drop will occur when the fuse or wire is in the preferred direction, in terms of sound quality. The speed of the signal is near light speed in copper. That is because ...drum roll.. the signal is photons, not electrons. If the electrons were the signal the whole thing would not work. You know, since it takes one hour for the electrons to travel one meter. That’s if the circuit is DC. Obviously in an AC circuit the electrons have a net velocity of Zero since they go back and forth along with the current
