eli5, If electricity is moving electrons, does the generator get them back?

698 views

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)?

Look I know I’m late to the party but one of the conceptual things just to keep in mind is that if you take something like an LED light, it doesn’t EAT electrons to make the light. Electrons come into the LED at a high energy and then the LED causes the electron to drop to a lower energy, the difference in those energy states is what is used to make light, but the electron is still there, just at a lower energy. Now it needs to become excited again (moved to a higher state) to be used, but the number of electrons don’t change.
