| We will start with the simplest circuit possible: a battery connected by a conducting wire (shown to the right). If we //__assume the battery is a mechanical battery__//, then we should have a constant amount of charge on each of the plates (one side of the battery being the positive plate and one side being the negative plate). Much like the example before, we would expect the electrons to flow from the negative plate through the wire to the positive end of the plate (with the only difference being that the chemical "conveyer belt" would now move the electrons from the positive plate back to the negative plate to start the cycle over again). | We will start with the simplest circuit possible: a battery connected by a conducting wire (shown to the right).

| If the electrons are moving, there has to be some sort of force that is making those charges move. From what we talked about before, we know we can write this force on the electron in terms of the electron charge and the electric field it is in: | If the electrons are moving, there has to be some sort of force that is making those charges move.
