Power Supplies

3. Opposition to the flow of electrical energy.
8. Designed to ensure a constant supply of quality electrical power to the computer system.
10. Used to connect to ATA hard drives, CD-ROM drives, and DVD drives; also called a Molex connector.
13. Provides power to the keyboard when the computer system is in sleep mode; also called soft power.
15. Electrical term used to describe the conductor paths inside the metal power supply case.
20. Occurs when a higher voltage than desired is present in the electrical system.
21. Used for 3 1/2 floppy drives; also called a mini connector.
22. Scale used to measure the volume of electron flow in a current.
24. Open industry power-management standard for desktops, laptops, and servers.

1. Power value of an ac circuit.
2. Amount of electrical pressure present in a circuit or power source.
4. Ability of a device or component to allow an unobstructed flow of electrical energy. current Amount of electron flow.
5. Common condition in which an ohmmeter reads resistance through a circuit even after a switch is opened.
6. Refers to electrical energy that flows in one direction, from negative to positive.
7. Occurs when no voltage is present.
9. Occurs when low voltage is present.
11. Does not normally conduct electricity until a certain voltage level is reached and then acts like a direct short, providing an alternate path for current.
12. Scale used in measuring electrical pressure.
14. Unit of resistance.
16. Has no negative or positive markings because it is in a state of constant change or alternating polarities.
17. Used during POST to verify the power supply is working properly.
18. Amount of electrical energy provided or used by equipment.
19. Electrical power distribution system that is designed to serve only computer equipment.
21. shape of glass or ceramic with a metal cap on each end.
23. Scale used in measuring electrical power.
