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. Mega






3. An IC package similar to a DIP - but smaller - which is designed for automatic placement and soldering on the surface of a circuit board.






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






5. Mega






6. Pico






7. 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.






8. 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.






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






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






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






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






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






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






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






16. Pico






17. P and Watt (W)






18. An electrical device used to store electrical charge.






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






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






21. 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.






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






23. Tera






24. Nano






25. Insulating board containing conductive tracks for circuit connections.






26. 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.






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






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






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






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






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






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






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






34. 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.






35. Giga






36. V or E and Volt (V)






37. P and Watt (W)






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






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






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






41. Micro






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






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






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






45. C and Farad (F)






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






47. Tool with an internal heating element used to heat surfaces being soldered to the point where the solder becomes molten.






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






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






50. Milli
