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






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






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






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






5. Nano






6. I and Ampere or Amp (A)






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






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






9. Tera






10. 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.






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






12. Milli






13. Pico






14. Kilo






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






16. 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.






17. Insulating board containing conductive tracks for circuit connections.






18. 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.






19. V or E and Volt (V)






20. 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.






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






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






23. Giga






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






25. 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.






26. Micro






27. An electrical device used to store electrical charge.






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






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






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






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






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






33. Milli






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






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






36. V or E and Volt (V)






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






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






39. 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.






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






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






42. Mega






43. 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.






44. Mega






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






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






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






48. 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.






49. Giga






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