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






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






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






5. Nano






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






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






8. Are and Ohms






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






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






11. 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.






12. V or E and Volt (V)






13. Giga






14. 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/






15. 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.






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






17. 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.






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






19. An electrical device used to store electrical charge.






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






21. Milli






22. Nano






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






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






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. I and Ampere or Amp (A)






27. 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.






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






29. Micro






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






31. Tera






32. 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.






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






34. C and Farad (F)






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






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






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






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






39. P and Watt (W)






40. Mega






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

45. Pico






46. Micro






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






48. Milli






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






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