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. Process of joining two metallic surfaces to make an electrical contact by melting solder (usually tin and lead) across them.






2. Component made of material that opposes flow of current and therefore has some value of resistance.






3. 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






4. I and Ampere or Amp (A)






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






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






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






8. Tera






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






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






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






12. Mega






13. 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.






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






15. C and Farad (F)






16. 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.






17. 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.






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






19. P and Watt (W)






20. Are and Ohms






21. Electronic test equipment that can perform multiple tasks. Typically one capable of measuring voltage - current - and resistance. More sophisticated modern digital multimeters also measure capacitance - inductance - current gain of transistors - and/






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






23. V or E and Volt (V)






24. 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.






25. 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.






26. Component made of material that opposes flow of current and therefore has some value of resistance.






27. A two terminal device that conducts in only one direction.






28. V or E and Volt (V)






29. Are and Ohms






30. Pico






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






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






33. 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.






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






35. Electronic test equipment that can perform multiple tasks. Typically one capable of measuring voltage - current - and resistance. More sophisticated modern digital multimeters also measure capacitance - inductance - current gain of transistors - and/






36. Milli






37. Micro






38. Mega






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






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






41. C and Farad (F)






42. Giga






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






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






45. Insulating board containing conductive tracks for circuit connections.






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






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






48. 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.






49. 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.






50. Insulating board containing conductive tracks for circuit connections.
