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. P and Watt (W)






2. 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.






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






4. 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






5. Micro






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






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






8. 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/






9. 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.






10. An electrical device used to store electrical charge.






11. Micro






12. 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.






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






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. Tera






16. Milli






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






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






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






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






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






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






23. Insulating board containing conductive tracks for circuit connections.






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






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






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






27. Tera






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






29. V or E and Volt (V)






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






31. Giga






32. An electrical device used to store electrical charge.






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






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






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






36. Are and Ohms






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. C and Farad (F)






39. V or E and Volt (V)






40. 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.






41. Insulating board containing conductive tracks for circuit connections.






42. 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.






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






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






45. P and Watt (W)






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






47. Mega






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






49. 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.






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