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






2. Insulating board containing conductive tracks for circuit connections.






3. Mega






4. 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.






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






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






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






8. Giga






9. Kilo






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






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






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






13. 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.






14. 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/






15. Numbers entered as a number from one to ten multiplied by a power of ten.






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






17. Pico






18. 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/






19. An electrical device used to store electrical charge.






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






21. 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.






22. 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.






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






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






25. C and Farad (F)






26. Micro






27. P and Watt (W)






28. I and Ampere or Amp (A)






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






30. A very common IC package with two parallel rows of pins intended to be inserted into a socket of through holes drilled in a printed circuit board.






31. A movement of electrical charges around a closed path or circuit.






32. 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.






33. An electrical device used to store electrical charge.






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






35. Numbers entered as a number from one to ten multiplied by a power of ten.






36. Nano






37. 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.






38. Insulating board containing conductive tracks for circuit connections.






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






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






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






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






43. 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.






44. Kilo






45. 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.






46. 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
