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 two terminal device that conducts in only one direction.






2. I and Ampere or Amp (A)






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






4. 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.






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






6. 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.






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






8. V or E and Volt (V)






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






10. Nano






11. 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






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






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






14. 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.






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






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






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






18. 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.






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






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






21. Giga






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






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






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






25. 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.






26. Micro






27. 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/






28. 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.






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






30. Milli






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






32. Insulating board containing conductive tracks for circuit connections.






33. Tera






34. Mega






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






36. Tera






37. 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






38. Micro






39. An electrical device used to store electrical charge.






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






41. Kilo






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






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






44. 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.






45. Nano






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






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






48. I and Ampere or Amp (A)






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






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