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






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






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






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






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






6. 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.






7. 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.






8. 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.

16. Mega






17. 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.






18. Giga






19. An electrical device used to store electrical charge.
