How a transistor works| 晶体管如何工作

Ben Eater gives a detailed look at how an NPN bipolar junction transistor works and what it does. It is an eleven-minute explanation aimed at building real understanding of the device.

Why HN likes it: HN commenters prefer it over other transistor explanations as an enlightening starting point that leads into building logic gates and a CPU.

“I found Ben Eater's videos on how semiconductors work and how transistors work interesting and enlightening.”
