MinutePhysics, one of my favorite YouTube channels, has done a collaboration project to provide an animated short on a scientifically correct version of the Children’s song, “Twinkle Twinkle Little Star.”
They are also offering an eBook at: http://minutephysics.com/twinkle
(Looks like if you pre-order the printed book, you’ll get a free copy of the eBook.)
One of the best ways to describe a transistor is as an “electronic switch.” They are solid state devices that make up almost everything in our world. This video by Veritasium, which is a bit older, covers how n and p-type transistors actually work.
This complements the Addohms videos on BJTs and MOSFETs, which are more about how to use them.
If you’ve never watched a Veritasium video, do yourself a favor and set aside a few minutes. He’s like the Alton Brown of science.
