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 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.






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






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






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






5. The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential - which is in the opposite direction of electron flow.






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






7. P and Watt (W)






8. Nano






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






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






11. An electrical device used to store electrical charge.






12. Milli






13. 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/






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






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






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. 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.






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






19. 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/






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






21. Giga






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






23. 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.






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






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






26. 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.






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






28. Are and Ohms






29. The direction of current flow associated with positive charge in motion. The current flow direction is from a positive to negative potential - which is in the opposite direction of electron flow.

37. 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.






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






39. 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.
