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






2. P and Watt (W)






3. 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.






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






5. Micro






6. Insulating board containing conductive tracks for circuit connections.






7. V or E and Volt (V)






8. Giga






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






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






11. An electrical device used to store electrical charge.






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






13. 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






14. 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.






15. 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.






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






17. C and Farad (F)






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






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






20. 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/






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






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






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






24. Nano






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






26. C and Farad (F)






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






28. Kilo






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






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






31. Pico






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






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






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






35. Tera






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






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






38. Kilo

43. Micro






44. 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.






45. Mega






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






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






48. Milli






49. I and Ampere or Amp (A)






50. P and Watt (W)
