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. F and Hertz (Hz) or Cycles per sec.






2. A circuit board for wiring temporary circuits - usually used for prototypes or laboratory work.






3. Micro






4. Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.






5. Tera






6. An IC package similar to a DIP - but smaller - which is designed for automatic placement and soldering on the surface of a circuit board.






7. The unwanted formation of a conductive path of solder between conductors.






8. The smallest particle of an element that still has the same characteristics as the element.






9. Giga






10. A circuit board for wiring temporary circuits - usually used for prototypes or laboratory work.






11. Metallic alloy of tin and lead that is used to join two metal surfaces.






12. A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value.






13. An electrical device used to store electrical charge.






14. The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential - which is in the opposite direction of electron flow.






15. A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values.






16. Mega






17. The instantaneous voltage of a waveform. Often used to mean maximum amplitude - or peak voltage - or a pulse.






18. Circuit that is capable of sensing and holding a signal until the event that changed the signal can be addressed.






19. The process of applying a thin coat of solder to materials prior to their being soldered; for example - application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering the conductor.






20. Term derived from 'transfer resistor.' Semiconductor device that can be used as an amplifier or as an electronic switch.






21. A solder connection that exhibits poor wetting and is characterized by a grayish - porous appearance due to excessive impurities in the solder - inadequate cleaning prior to soldering - and/or the insufficient application of heat during the soldering






22. A group of flip-flops (typically 4 or 8) that are arranged so that the values stored in the flip-flops are shifted from one flip-flop to the next for every clock.






23. Mega






24. Abbreviation of System International - a system of practical units based on the meter - kilogram - second - ampere - Kelvin - mole - and candela.






25. Pico






26. A circuit the produces a digital output signal that is half the frequency of the input.






27. A floating point system in which numbers are expressed as products consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three.






28. A way of representing a physical quantity by a series of binary numbers. A digital representation can have only specific discrete values.






29. V or E and Volt (V)






30. The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential - which is in the opposite direction of electron flow.






31. Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.






32. Nano






33. Abbreviation of System International - a system of practical units based on the meter - kilogram - second - ampere - Kelvin - mole - and candela.






34. Signal in the form of a rectangular pulse train or a square wave.






35. Any material that allows the free movement of electric changes - such as electrons - to provide an electric current.






36. P and Watt (W)






37. Kilo






38. Insulating board containing conductive tracks for circuit connections.






39. Term derived from 'transfer resistor.' Semiconductor device that can be used as an amplifier or as an electronic switch.






40. A floating point system in which numbers are expressed as products consisting of a number greater than one multiplied by an appropriate power of ten that is some multiple of three.






41. Signal in the form of a rectangular pulse train or a square wave.






42. A square IC package with leads on all four sides designed for surface mounting on a circuit board.






43. A series of logic 1s and 0s plotted as a function of time.






44. The process of applying a thin coat of solder to materials prior to their being soldered; for example - application of a light coat of solder to the filaments of a conductor to hold the filaments in place prior to soldering the conductor.






45. A square IC package with leads on all four sides designed for surface mounting on a circuit board.






46. A way of representing some physical quantity - such as temperature or velocity - by a proportional continuous voltage or current. An analog voltage or current can have any value within a defined range.






47. Micro






48. The unwanted formation of a conductive path of solder between conductors.






49. Giga






50. Any material that allows the free movement of electric changes - such as electrons - to provide an electric current.
