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






2. 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/






3. I and Ampere or Amp (A)






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






5. P and Watt (W)






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






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






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






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






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






11. I and Ampere or Amp (A)






12. An electrical device used to store electrical charge.






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






14. Insulating board containing conductive tracks for circuit connections.






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






16. Kilo






17. Milli






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






19. 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.






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






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






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






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

26. Milli






27. 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.






28. Mega






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






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

38. 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.






39. 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.






40. 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.






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