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. I and Ampere or Amp (A)






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






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






4. 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.






5. Mega






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






7. I and Ampere or Amp (A)






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






9. 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/






10. 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.






11. V or E and Volt (V)






12. C and Farad (F)






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






14. Pico






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






16. 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.






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






18. 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/






19. Insulating board containing conductive tracks for circuit connections.






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






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






22. 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.






23. Pico






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

30. 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.






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






32. Tera






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






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






35. Mega






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






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






38. Nano






39. Tera






40. P and Watt (W)






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

44. Insulating board containing conductive tracks for circuit connections.






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






46. Kilo






47. 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.






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






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






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