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 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.






2. Are and Ohms






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






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






5. Milli






6. V or E and Volt (V)






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






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






9. Pico






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






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






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






13. Tera






14. Are and Ohms






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






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






17. Mega






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






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






20. Mega






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






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 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






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






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






26. Kilo






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






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






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






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






32. I and Ampere or Amp (A)






33. Giga






34. P and Watt (W)






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






36. 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.






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






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






39. 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.






40. Milli






41. 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.






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






43. Pico






44. 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.
