- The positive and negative charge at the two cell terminals are
- attracted to each other. The opposite charges cannot reach each
- other through the cell because it is acting as a good insulator.

- The light has come on so we know that current is flowing in the circuit.
- Current is in fact charge moving through the wires from one terminal
- of the cell to the other.
