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

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






20. 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.






21. 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.






22. Insulating board containing conductive tracks for circuit connections.






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






24. An electrical device used to store electrical charge.






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






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






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






28. 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
