So a generator is magnets and copper coil yeah? They make electricity and electricity is moving electrons. Power generators and electric stations are kilometres away. Do the copper coils get their electrons back?
Won’t the copper coil run out of electrons. How the electrons come back (if they do)?
In: 117
With direct current (DC) the electrons do indeed move out of the negative lead and into the positive lead of the power source. They move very slowly (millimeters per second or less). With alternating current (AC) they jiggle back and forth and don’t really move along the wire, but the electromagnetic wave moves which propagates energy and makes the electrons down the line jiggle as well.
