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. Insulating board containing conductive tracks for circuit connections.






2. Nano






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






4. Nano






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






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






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






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






9. 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






10. 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.






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






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






13. An electrical device used to store electrical charge.






14. 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.






15. Micro






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






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






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






19. Micro






20. 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.






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






22. 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.






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






24. 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.






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






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






27. Milli






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






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






30. Are and Ohms






31. C and Farad (F)






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






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






34. Kilo






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






36. 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.






37. 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.






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






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






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






41. 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.






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






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






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






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






46. P and Watt (W)






47. P and Watt (W)






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






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






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