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. Are and Ohms






3. V or E and Volt (V)






4. Insulating board containing conductive tracks for circuit connections.






5. 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.






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






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






8. An electrical device used to store electrical charge.






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






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






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






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






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






14. P and Watt (W)






15. Milli






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






17. I and Ampere or Amp (A)






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






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






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






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






22. Giga






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






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






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. I and Ampere or Amp (A)






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






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






29. 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.






30. Nano






31. 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.






32. 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.






33. C and Farad (F)






34. Pico






35. 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.






36. Micro






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






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






39. Tera






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






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






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






43. Giga






44. P and Watt (W)






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






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






47. 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.






48. Are and Ohms






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






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