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






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






3. Kilo






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






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






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






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






8. Milli






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






10. Are and Ohms






11. 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.






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






13. Mega






14. An electrical device used to store electrical charge.






15. Kilo






16. 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.






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






18. 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.






19. Giga






20. Nano






21. An electrical device used to store electrical charge.






22. Milli






23. An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements - shaped like a figure-8 - which can be used to display decimal digits and other characters by turning on the appropriate elements.






24. 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.






25. 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.






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






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






28. Giga






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






30. Pico






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






32. Nano






33. Micro






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






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






36. 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.






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






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






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






40. I and Ampere or Amp (A)






41. C and Farad (F)






42. Micro






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






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






45. P and Watt (W)






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






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






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






49. An array of seven independently controlled light-emitting diodes (LED) or liquid crystal display (LCD) elements - shaped like a figure-8 - which can be used to display decimal digits and other characters by turning on the appropriate elements.






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