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






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






3. Nano






4. Kilo






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






6. C and Farad (F)






7. Are and Ohms






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






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






10. Milli






11. Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.






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






13. Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.






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

23. Pico






24. Giga






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






26. 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.






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






28. Giga

43. C and Farad (F)






44. Mega






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






46. 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.






47. Micro






48. 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.






49. P and Watt (W)






50. 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
