Every atom in the copper wire has electrons. (a full complement of them needed to ballance the positive charge of their nucleus. The outer (valence) electrons are used by more than one atom at a time. They wander in the wire. EMF electro motive force (volts) put into the wire from end to end with a battery, or from the middle with a moving magnetic field, pushes them along. They force the ones closest to the end of the wire through a load(light bulb filiment) where the restriction causes them to be heating the filiment as they force their way through. Then they go back to the other end of the battery, (or wire in a generator), to start again. However they are playing musical chairs all along the way, not zipping at 300 000 000 meters per second. A single electron called Wilber, for example, might get lost and ram into an atom and displace an inner layer electron and never be in the system again. while another, called fred, might wander through and be back at the battery positive side in 4 hours. The speed of the musical chairs effect, is speed of light (or so) but the people move much slower. JimN
