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






2. P and Watt (W)






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






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






5. Mega






6. V or E and Volt (V)






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






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






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






10. Nano






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






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






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






14. 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.






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






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






17. Milli






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






19. 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/






20. Insulating board containing conductive tracks for circuit connections.






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






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






23. Kilo






24. 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/






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






26. 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.






27. 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.






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






29. An electrical device used to store electrical charge.






30. C and Farad (F)






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






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






33. Are and Ohms






34. I and Ampere or Amp (A)






35. Giga






36. Milli






37. Pico

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






40. 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.






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






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






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






44. An electrical device used to store electrical charge.






45. P and Watt (W)






46. Insulating board containing conductive tracks for circuit connections.






47. Kilo






48. 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






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