Electricity

5. Like charges _________ one another.
6. The build up of electric charge caused by friction. The charges remain stationary on the object.
7. A continuous closed path which allows electricity to flow through.
8. A method of connecting electrical components (eg. bulbs and cells) so that the current divides and part passes through each component.
9. Electricity moving through an electrical circuit.
10. A measure of the electrical potential energy of a cell. Ie. The amount of ‘push’ in a circuit.
13. A method of connecting electrical components (eg bulbs and cells), so that the current passes through one then the other.
14. A device used to measure the amount of electricity in a circuit. It is connected in series.
15. A way of drawing an electric circuit using symbols.
17. A substance that does not allow electricity to flow through.
18. A Perspex rod becomes positive in charge after being rubbed with a silk cloth because it loses electrons.
19. The amount of electricity in a circuit. Measured in amps.

1. A substance that allows electricity to flow through.
2. Unlike charges _________ one another.
3. Results when an object gains (negative charge) or loses electrons (positive charge)
4. Resistance to the flow of electric current through a conductor; good conductors have low resistance.
11. Tiny particles carrying a negative charge; they surround the nucleus of an atom.
12. An metal that is an excellent conductor of electricity.
16. A device used to measure the amount of ‘push’ or energy in a circuit.
18. A plastic that is a good electricity insulator.
