Electricity doesn't move at the speed of light?!?! I recently have read (in several aticles) that have presented evidence that "electrons" do not actually flow at the speed of light (and electron movement is thought to be "electricity"). If you argue that "Yes electricity DOES flow at the speed of light", then you must specify which of the 5 definitions of electricity you picked to represent "electricity". The electrons move actually very slow in the conductor, 0.2 cm p/s I was told. But the effect of the movement across the whole of the conductor is felt at once through the kinetic energy of the movement. There are also many logical things (That we don't ususaly think about (***Almost an Oxymoron***)) about how it is not possible for the electrons to move at the speed of light. Number one: Electrons have mass. Nothing that has mass can travel at the speed of light. Second: Even light slows down in a volume, it only travels at c in a vaccum. Copper or other conductors are even more dense than air(which slows down light), and thus electrons definately could not move at the speed of light in the volume of the conductor. Third: If they (electrons) were even moving at speeds half that of c the conductor would get so hot it would melt, the resistors would overload + burn, stuff would probably catch on fire, and (of course joking) it could even go plasma ;-)! All my points/comments (except for the one about plasma, Duh) hold a hard to debate validity in them. I would like to see other peoples comments on this.
