Quiz Day Friday Finale: Transistors and FETs

The week is at its end as is Quiz Day Friday. You are either relieved, surprised, or disappointed. All understandable emotions.
Trust me.

For the past ten weeks, we’ve presented clever quizzes created by Electro-Tech-Online community members including: 3vO,DerStrom, Ian Rogers, Pommie, MrB, Reload Ron, JimB, MrAl, and ericgibbs.  These are just a few of the top Electro-Tech-Online members who work, live, and breathe electronics to the point where they can’t help but help fellow engineers.

What is this virtual venue, you ask? Electro-Tech-Online is an electrical engineering membership forum where you can ask questions and get answers from engineers on everything from microcontrollers, renewable energy, and automotive electronics, to circuit simulation and design. There are also forums for sharing information about repairing electronics or getting help finding datasheets, manuals, or parts.

For those of you who have skated through every quiz…kudos and thanks for participating. If you haven’t had the opportunity to finish or take a Friday quiz, you can start or restart now by clicking on the links below to the previous quizzes.

Quiz V1.0 on General Electronic and Electrical Engineering
