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. Are and Ohms






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






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






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






5. Nano






6. 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/






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






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






9. Mega






10. An electrical device used to store electrical charge.






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






12. Micro






13. 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.






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






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






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






17. C and Farad (F)






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






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






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






21. An electrical device used to store electrical charge.






22. Pico






23. 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.






24. Are and Ohms






25. 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.






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






27. Micro






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






29. C and Farad (F)






30. I and Ampere or Amp (A)






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






32. Insulating board containing conductive tracks for circuit connections.






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






34. Milli






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






36. 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.






37. V or E and Volt (V)






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






39. 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.






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






41. 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.






42. 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.






43. P and Watt (W)






44. Insulating board containing conductive tracks for circuit connections.






45. Tera






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






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






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






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






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