Physics, Astronomy & Cosmology / Re: Do the electrons that generate an electric current come from the wire's atoms?« on: 13/01/2020 18:09:40 »
Rakesh reached out with a couple of questions on electric current:The electrons in a conductor exist in sea of electrons. They aren't bound to particular atoms.
What is the speed of electric current? When elections flow - do they come out from the atoms and flow as electric current? Is it not true that when electrons come out from atoms, light and energy is released? So why don't electric wires change their color?
Can you help?
