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






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






3. Insulating board containing conductive tracks for circuit connections.






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. Are and Ohms






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






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






8. 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.






9. Coding system of colored stripes on a resistor to indicate the resistor's value and tolerance.






10. Mega






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






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






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






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






15. Micro






16. 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






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






18. Tera






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






20. C and Farad (F)






21. 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.






22. 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.






23. C and Farad (F)






24. Giga






25. Kilo






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






27. 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.






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






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






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






31. Giga






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






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






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






35. Micro






36. 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.






37. Mega






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






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






40. An electrical device used to store electrical charge.






41. I and Ampere or Amp (A)






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






43. P and Watt (W)






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






45. 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






46. I and Ampere or Amp (A)






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






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. Pico






50. An electrical device used to store electrical charge.
