Subject : engineering
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. 'Common Mode Voltage.' The voltage which is tolerable between signal and ground.






3. (DC); Electrical current that flows consistently in one direction only.






4. The delayed period of time when outputs are turned off when power is initially applied.






5. Applying molecular physics to electronics.






6. The mechanism of a switch which operates the contacts.






7. The magnitude and time phase of a quantity - represented by a plotted line.






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






9. One millionth of a meter.






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






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






12. A fluctuation in the intensity of a steady current.






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






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






15. The unit by which electrical resistance is measured. One ohm is equal to the current of one ampere which will flow when a voltage of one volt is applied






16. The increase of the power level - current or voltage of a signal. In an amplifier it is the ratio of the output to the input signal levels.






17. One millionth of a volt.






18. 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.






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






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






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






22. -459.67






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






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






25. ISO;






26. An arrangement of any of various conductors through which electric current can flow from a supply current.






27. A switch in a controller that manually resets after exceeding the controllers limit.






28. A reference point at zero potential with respect to the earth. In an electronic circuit it is the common return path for electric current. A conducting connection between the earth and an electrical circuit or electrical equipment. Also - the negativ






29. Normally Open.






30. IEEE;






31. 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.






32. A coil of wire wound about a magnetic material - such as iron - that produces a magnetic field when current flows through the wire.






33. Symbol used to denote transmitter.






34. 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.






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






36. NFPA;






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






38. A sensor or switch with the ability to detect it's relationship to a metal target without making physical contact.






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






40. An electrically conductive fused salt or a solution where the charge is carried by ionic movement.






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






42. A device used to store electrical energy in an electrostatic field until discharge.






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






44. Pressure that is less than atmospheric pressure.






45. That part of a circuit which is physically interconnected.






46. The interaction of magnetism and electrical current.






47. The power of one watt operating for one hour - and equal to 3 -600 joules.






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






49. Mm; One thousandth of a meter.






50. A full path of electrical current from a voltage source that passes completely from one terminal of the voltage source to another.
