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. V or E and Volt (V)






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






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






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






5. C and Farad (F)






6. 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.






7. 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






8. Micro






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

18. Are and Ohms






19. Pico






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






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






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






23. P and Watt (W)






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






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. An electrical device used to store electrical charge.






28. C and Farad (F)






29. Insulating board containing conductive tracks for circuit connections.






30. I and Ampere or Amp (A)






31. Pico






32. 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.






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






34. Mega






35. I and Ampere or Amp (A)






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

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






39. Are and Ohms






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






41. Micro






42. 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.
