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






3. 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.






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






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






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






8. 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.






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






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






11. C and Farad (F)






12. 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/






13. Pico






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






15. Giga






16. Insulating board containing conductive tracks for circuit connections.






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






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






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






20. Tera






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






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






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






24. An electrical device used to store electrical charge.






25. An electrical device used to store electrical charge.






26. 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/






27. 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.






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






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






30. C and Farad (F)






31. 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.






32. I and Ampere or Amp (A)






33. 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.






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






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






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






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






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






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

44. Mega






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






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






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






48. Kilo






49. Milli
