Hey people,
I'm learning about FETs, and after remembering the classical image of a Bipolar transistor and of the FET, (image on http://www.electronics-tutorials.ws/transistor/tran_5.html I really like this site) I came up with a general question: in the bipolar, if both collector and emitter are with the same impurities, in the images symmetrical, why, or how, we differentiate the collector from the emitter? The same question on FETs, related to the drain and source. What am I misunderstanding? What is wrong or hidden?
Thanks in advance.
