6. A cell is an "electrical power supply". It converts stored chemical energy into electrical potential energy.
7. A battery is a device that stores chemical energy and converts it to electrical energy.
8. An open circuit is one where the continuity has been broken by an interruption in the path for current to flow. A closed circuit is one that is complete, with good continuity throughout.
9. An electrical switch controls the flow of electrical current within a circuit.
