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 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.






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. 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.






4. Kilo






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






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






7. Giga






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






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






11. Are and Ohms






12. C and Farad (F)






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






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






15. I and Ampere or Amp (A)






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






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






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






19. 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.






20. Micro






21. Pico






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






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






24. Insulating board containing conductive tracks for circuit connections.






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






26. 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/






27. Giga






28. 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






29. 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.






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






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






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






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






34. Mega






35. 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.






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






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






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






39. Insulating board containing conductive tracks for circuit connections.






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






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






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






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






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






45. Kilo






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






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