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






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






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






4. C and Farad (F)






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






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






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






8. Micro






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






10. Giga






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






12. An electrical device used to store electrical charge.






13. 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.






14. Giga






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






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






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






18. Light-emitting diode. An electronic device that conducts current in one direction only and illuminates when it is conducting.






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






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






21. Insulating board containing conductive tracks for circuit connections.






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






23. Milli






24. I and Ampere or Amp (A)






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






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






27. P and Watt (W)






28. Tera






29. I and Ampere or Amp (A)






30. V or E and Volt (V)






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






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






33. 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/






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






35. Insulating board containing conductive tracks for circuit connections.






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






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






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






40. V or E and Volt (V)






41. 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.






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






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






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






45. Micro






46. P and Watt (W)






47. Are and Ohms






48. 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.
