How does a transistor work?

#1 [Video Link] This is a good six-minute video that explains how transistors work. I liked the description of N- and P-type doping. (Via Adafruit) READ THE REST


That was good but disappointed not one mention of amplification.


The amplification is implied wink


Small fail in the first sentence. "over 100 million transistors in a phone" - but there's a transistor for every bit in the flash memory - 16GB = 16 billion transistors just there, to say nothing of the rest of the phone.

Other than that, very good and interesting.
