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. V or E and Volt (V)






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






3. An electrical device used to store electrical charge.






4. 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.






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






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






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






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






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






10. Mega






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






12. Kilo






13. 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.






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






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






16. Tera






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






18. Are and Ohms






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






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






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






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






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






24. Mega






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






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






27. Nano






28. Giga






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






30. Nano






31. 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.






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






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






34. 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.






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






36. Are and Ohms






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






38. C and Farad (F)






39. 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/






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






41. Milli






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






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






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






45. 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.






46. Insulating board containing conductive tracks for circuit connections.






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






48. 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.






49. V or E and Volt (V)






50. 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.
