25 Questions

1. A unit of POWER. 1 kilowatt = 1 -000 watts

2. One millionth of an ampere.

3. Several secondary cells connected together for either a greater voltage or current output.

4. (EMF) The force created by an electric generator (or by other means) which causes current to flow. (Same as Voltage - Volts - Electric Potential - Pressure).

5. A single electron or one of two or more electrons in the outer shell of an atom that is responsible for the chemical properties of an atom.

6. A current which reverses in direction at regularly recurring intervals - the total flow in one direction being equal to that in the other direction.

7. A current limiting device designed to melt and break the circuit when a specified current is exceeded. (The weakest point in a circuit)

8. The process of producing an electromotive force in a conductor as a result of the cutting of magnetic lines of force by a conductor.

9. (Lode Stone) Certain type of mineral ore which has the natural Properties of a magnet.

10. Positive charge of electricity. Located in the nucleus of the atom.

11. The condition where the free electrons are caused to move in the same direction along or through a conductor.

12. The area surrounding a magnet in which magnetic properties are exhibited

13. A device used to change the voltage of an alternating current circuit.

14. Coil connected to the source of power on a transformer.

15. 1.Material itself (Atomic Structure - Good conductor or Bad) 2.Length of the conductor 3.Cross - sectional area (Size) 4.Temperature

16. A device which capacity is its chief electrical property; a device for storing or holding an electric charge; a capacitor.

17. A transformer designed to raise the voltage of an alternating current. Most common use; In a generating plant to raise the voltage.

18. Transformer coil connected to the load. (Output side of a transformer regardless of voltage).

19. One millionth of an ohm.

20. The space around a magnet in which the magnetic force is felt.

21. A circuit with two or more paths for the current to take.

22. A transformer designed to lower voltage of an alternating current. Most common type of transformer used on a power system.

23. Total and complete opposition to the flow of electrons

24. The magnetism which a material retains after the magnetic force which magnetized it has been removed.

25. One million ohms.
