- 2. A common material used to coat electric wires because it is a safe insulator.
- 4. A device that converts electrical energy into light energy.
- 6. A complete and closed path through which an electric current can flow.
- 7. The state of a circuit when the path is broken and electricity cannot flow.
- 9. A widely used metal for making electric wires because it is an excellent conductor.
- 11. A portable electric lamp that uses cells and a small bulb to provide light.
- 13. A material that allows electric current to pass through it easily, such as copper.
- 14. The state of a circuit when the switch is in the 'on' position and electricity can flow.

- 1. The two points (positive and negative) on an electric cell where wires are connected.
- 3. A simple device used to either break an electrical circuit or complete it.
- 4. A device that provides electricity by converting chemical energy into electrical energy.
