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






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






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






4. Tera






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






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






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






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






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






10. Insulating board containing conductive tracks for circuit connections.






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






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






13. 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.






14. 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.






15. I and Ampere or Amp (A)






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






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






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






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






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






21. C and Farad (F)






22. 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/






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






24. Giga






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






26. 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.






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






28. Are and Ohms






29. 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.






30. Micro






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






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






33. 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.






34. Nano






35. Pico






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






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






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






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






40. 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






41. 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.






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






43. 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.






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






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






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






47. I and Ampere or Amp (A)






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






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






50. Tera
