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.

31. I and Ampere or Amp (A)






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






33. 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






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






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

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






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






47. 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/






48. 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.






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






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