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






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






3. Giga






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






5. An electrical device used to store electrical charge.






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






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






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






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






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






11. P and Watt (W)






12. Milli






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






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






15. Nano






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






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






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






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






20. I and Ampere or Amp (A)






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. Insulating board containing conductive tracks for circuit connections.






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






24. I and Ampere or Amp (A)






25. V or E and Volt (V)






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






27. Giga






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






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






30. Nano






31. Mega






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






33. An electrical device used to store electrical charge.






34. 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.






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






36. 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.






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






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






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






40. Pico






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






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






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






44. Micro






45. P and Watt (W)






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






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






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






49. C and Farad (F)






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