25 Questions

1. The smallest particle to which an element can be reduced and still retain its characteristics.

2. The unit of measurement of electric potential.

3. A material that offers a high resistance to electric current flow.

4. A material that allows electric current to flow through it easily.

5. The unit of measurement of electric resistance.

6. The unit of electric charge - which is the basic unit of measurement for current flow in an electric circuit.

7. The movement of electric charge; the flow of electrons through an electric circuit.

8. A circuit that forms a direct path across a voltage source (with little or no resistance) so that a very high and possibly unsafe electric current flows.

9. Current flows in one direction only.

10. The difference of electrical potential between to points on a circuit

11. The rate at which work is done.

12. The part of an electric system that shows whether the system is on or off or that a specific quantity is present.

13. The method by which loosely held atoms are bound together in metals.

14. The unit of measurement of electric power.

15. A circuit that has a broken path so that no electric current can flow through it. A circuit with infinite resistance.

16. Electricity at rest caused by accumulation of either positive or negative electric charge.

17. Areas through which electrons move; designated as s - p - d - and f.

18. A neutrally charged atom

19. Electrons in the outer orbit of an atom.

20. A unit of electric charge that represents a large number of electrons. ~ 6.28 x 1018 electrons

21. Electric force - or pressure - that causes current to flow in a circuit.

22. Current periodically reverses direction

23. Energy that exists because of movement.

24. A positively charged atom

25. A charge on a material that is said to be either positive or negative.
