Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A high-intensity incandescent lamp with a quartz bulb containing an inert gas of iodine or bromine vapor.






2. A three mode control consisting of time Proportioning - Integral and Derivative rate action.






3. Volt-ohm Meter.






4. Resistance Temperature Detector.






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






6. A switch with contacts that are made with actuating force and released when that force is removed.






7. The interaction of magnetism and electrical current.






8. The part of a circuit that supplies power to the entire circuit or part of the circuit. Usually a separate unit that supplies power to a specific part of the circuit in a system.






9. A circuit conductor that is grounded to become part of the electric circuit by design and intent.






10. The measure of the ability of a material or substance to carry electrical current.






11. A process that is kept at a constant temperature.






12. Silicone Controlled Rectifier.






13. The unit of power. One watt equals one joule per second - 1/746th horsepower.






14. 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.






15. Ultra High Frequency






16. NEC: A set of regulations pertaining to electrical installation and design in the interest of the protection of life and property. The NEC is adopted by NFPA and approved by ANSI. It is the preferred standard of guidelines used by most electrical reg






17. The maximum temperature at which a device can be safely operated.






18. Kva; One thousand volt amps.






19. A form of control where the power supplied to a process is controlled by limiting the phase angle of the line voltage.






20. The range of voltage needed to maintain operation of a control or device.






21. 'American Wire Gauge' system used to determine wire size.






22. One of the very small discrete packets into which many forms of energy are subdivided.






23. A form of energy produced by the flow of particles of matter and consists of commonly attractive positively (protons [+]) and negatively (electrons [-]) charged atomic particles. A stream of electrons - or an electric current.






24. An interconnected arrangement of parts for carrying high-voltage electricity.






25. The current that is gained by a transistor when it is connected in a common emitter circuit.






26. To close an electrical circuit. To establish an electrical circuit through the closing of a contact - switch or other related device.






27. A device that transfers power or energy from one system to another - such as taking a physical quality and changing it to an electrical signal.






28. FM; ~LINK~






29. IEEE;






30. A sudden and unwanted increase or decrease of supply voltage or current.






31. A positive (+) electrode. The point where electrons exit from a device to the external electric circuit.






32. A silicone semiconductor that maintains a fixed voltage in a circuit.






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






34. The voltage that is applied across a semiconductor junction to permit forward current through that junction and the device. Forward voltage is also known as 'bias.'






35. NEMA;






36. A unit of energy in solid-state physics with mass and momentum but that does not exist as a free particle.






37. A panel meter with zero and span adjustments - commonly scaled for signals such as 1-5 volts - 4-20mA - etc.






38. An anode (+) or cathode (-) conductor on a device through which an electric current passes.






39. When there is current through a semiconductor p-n junction it is the resistance of a forward-biased junction.






40. The adjustment of a display that results are zero on the display corresponding to a non-zero signal.






41. An area in which combustible or flammable mixtures are or could be present.






42. Electric and magnetic force field that surrounds a moving electric charge.






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






44. Pounds per square inch gage. Pressure in relationship to the ambient air pressure>






45. An electromagnetic radiation produced when the inner satellite electrons of heavy atoms have been excited by collision with a stream of fast electrons return to their ground state - giving up the energy previously imparted to them.






46. Or Hertz; The measurement of the time period of one alternating electric current. In the United States this is commonly 60 cycles per second - or 60 Hertz.






47. A rise and fall of voltage - current - or other faction that would be constant under normal conditions. A pulse that is intentionally induced will have a finite duration time.






48. A hypothetical nuclear of a quark plus an antiproton.






49. See; 'Maximum Power Rating'.






50. A device having two terminals and has a low resistance to electrical current in one direction and a high resistance in the other direction.
