25 Questions

1. IEEE;

2. A meter used to measure electrical resistance in units of ohms.

3. A full-wave rectifier where the diodes are connected in a bridge circuit. This allows the current to the load during both the positive and negative alternating of the supply voltage.

4. A negative (-) electrode. The point of entry of electrons into a device from an external circuit. The negative electrode of a semiconductor diode.

5. A circuit which may have one or many resistors and/or other various devices connected in a series so that the current has only one path to follow.

6. A unit of electric charge. The amount of charge conveyed in one second by one ampere.

7. Commonly used in generators and motors - it is an electromagnet formed from a coil of insulated wire that is wound around a soft iron core.

8. Ultra High Frequency

9. A device - instrument or component that will not produce any spark or thermal effects under any conditions that are normal or abnormal that will ignite a specified gas mixture. Electrical and thermal energy limits are at levels incapable of causing i

10. A hypothetical basic subatomic nuclear particle believed to be the basic component of protons - neutrons - etc.

11. A solid-state switching device used in switching AC wave forms.

12. (AC); Electrical current that changes (or alternates) in magnitude and direction of the current at regular intervals.

13. An electrical circuit that increases the power - voltage or current of an applied signal.

14. A Solid State relay is a switching device that completes or interrupts a circuit electrically and has no moving parts. A Mechanical relay is an electromechanical device that closes contacts to complete a circuit or opens contacts to interrupt a circu

15. In a three phase connection all three phases are connected in series thus forming a closed circuit.

16. Inspection - analysis and action required to ensure quality of output.

17. The unit for capacitance. A capacitor that stored one coulomb of charge with one volt across it will have a value of one farad.

18. The difference in potential measured between two points caused by resistance or impedance.

19. A solid-state switching device for semiconductors to convert AC current in one of two directions controlled by an electrode.

20. The amount of energy released in a nuclear reaction. It is expressed in atomic mass units - or in million electron volts (MEV).

21. The basic of thermal energy. The work done by the force of one newton acting through a distance of one meter.

22. An ionized gas containing about equal numbers of positive and negative charges - which is a good conductor of electricity - and is affected by a magnetic field.

23. Voltage; The unit of electromotive force (EMF) that causes current to flow. One volt causes a current of one amp through a resistance of one ohm.

24. The interaction of magnetism and electrical current.

25. The act of the opening of an electrical circuit.
