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. 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.






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






3. Milli






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






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






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






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






8. I and Ampere or Amp (A)






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






10. V or E and Volt (V)






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






12. C and Farad (F)






13. Nano






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






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






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






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






18. Pico






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






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






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






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






23. Milli






24. Are and Ohms






25. 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.






26. 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.






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






28. 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.






29. 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/






30. Insulating board containing conductive tracks for circuit connections.






31. Giga






32. 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.






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






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






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






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






37. 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.






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






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






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






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






42. C and Farad (F)






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






44. P and Watt (W)






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






46. P and Watt (W)






47. Mega






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






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






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