You should ask that 'how many electrons per bit' question on the wikipedia reference desk(, Fri 11 Sep 2009, 0:54, archived)
I could, but I need to figure out how to frame the question. The Wikipedia culture scares me.I have a feeling the answer is going to begin with something like, "that's not how it works, gnaaa gnaaa gnaaa"
Maybe I'll post the question on Yahoo Answers, so some ignorant redneck can make fun of my haircut when he can't figure out the question.

They're not the sneering type, really.A question on the science desk yesterday was "it have seen that if an ufo is looked anywhere , then it is seen that aliens use zigzag motion to come at the earth, so why can not use this type of maotion to go to any other planet?" ... and they did their best to guess at what this meant and answer the question.

It's going to be long. 60 to 100m I'd bet.You've got speed of light(on copper) divided by bandwidth time or the length of a clock interval
times the number of state changes per byte(datum plus stops and markers) times packet length. I think.

I understood that. Does that make me a nerd?So if I could learn the velocity of propagation over UTP copper, and the oscillation rate of the modulator...
I think I can work it out then. I WAS actually looking at the wrong way :P

It's not going to be the speed of light.Maybe a third, or a half, or two thirds. This depends on something or other to do with wires, I'm pretty sure, yup.

Yeah, on copper makes a big difference.The local speed of propagation/light/energy is slower. 66%ish for rough calculations.

You're mostly right. I used to work in Cable TV, We would see up to 80% for very good coaxial cablingTwisted pair cabling is a bit lower.
