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. Nano






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






3. Micro






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






5. A movement of electrical charges around a closed path or circuit.






6. 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.






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






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






9. Tera






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






11. Are and Ohms






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






13. Insulating board containing conductive tracks for circuit connections.






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






15. 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.






16. 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.






17. V or E and Volt (V)






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






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






20. 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.






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






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






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






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






25. Are and Ohms






26. Nano






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






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






29. V or E and Volt (V)






30. Mega






31. Giga






32. 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.






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






34. 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.






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






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






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






38. 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/






39. Kilo






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






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






42. An electrical device used to store electrical charge.






43. Milli






44. Kilo
