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 movement of electrical charges around a closed path or circuit.






2. Insulating board containing conductive tracks for circuit connections.






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






4. V or E and Volt (V)






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






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






7. 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.






8. 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.






9. 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.






10. C and Farad (F)






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






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






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






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






15. Nano






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






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






18. 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.






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






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






21. Giga






22. 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.

31. 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






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






33. Micro
