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 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






2. Are and Ohms






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






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






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






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






7. 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.






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






9. 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.






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






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






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






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






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






15. Milli






16. 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.






17. Pico






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






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






20. 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/






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






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






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






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






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






26. Insulating board containing conductive tracks for circuit connections.






27. Kilo






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






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