Digital Electronics Vocab

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






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






3. Mega






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






5. 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.






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






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






8. 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.






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






10. Insulating board containing conductive tracks for circuit connections.






11. An electrical device used to store electrical charge.






12. Milli






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






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






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






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






17. Kilo






18. 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.






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






20. Giga






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. 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/






23. C and Farad (F)






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






25. P and Watt (W)






26. V or E and Volt (V)






27. Giga






28. 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.






29. I and Ampere or Amp (A)






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






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






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






33. Micro






34. Tera






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






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






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






38. I and Ampere or Amp (A)






39. 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.






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






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






42. Micro






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






44. P and Watt (W)






45. Pico






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






47. Nano






48. 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/






49. Are and Ohms






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