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






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






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






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






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






6. 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.






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






8. 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.






9. An electrical device used to store electrical charge.






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






11. 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.






12. Kilo






13. Nano






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






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






16. Nano






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






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






19. Micro






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






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






22. C and Farad (F)






23. V or E and Volt (V)






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






25. 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.






26. P and Watt (W)






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






28. Giga






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






30. Giga






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






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






33. P and Watt (W)






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






35. I and Ampere or Amp (A)






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






37. 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/






38. Tera






39. 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.






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






41. Mega






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






43. 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.






44. Insulating board containing conductive tracks for circuit connections.






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






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






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






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






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






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