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






2. P and Watt (W)






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






4. Giga






5. I and Ampere or Amp (A)






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






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

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






13. 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.






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






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






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

18. Mega






19. 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.






20. A protective device in the current path that melts or breaks when current exceeds a predetermined maximum value.






21. C and Farad (F)






22. 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






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






24. C and Farad (F)






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






26. 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.
