For quite some time I've been having the same problem with transistor amplifiers: I read and understand the relevant information from books, websites, etc. I'm able to do all the analysis exercises. But as soon as I attempt to apply it all I realize that I still have so many questions and doubts that I'm incapable of using any of it in my designs. And I'm not talking about complicating things by using PNP instead of NPN; or using common-base and emitter-follower... I'm talking about simple common-emitter designs with just a NPN BJT.
I think half of the problem is that most books and websites teach you how to analyze amplifiers, but they don't say a word about how to design them. I now began to study the section on transistors from this website, which at least gives some examples of practical applications, but there are still things I feel were left out, things that differ from other sources and are confusing me, and things that I still have no idea where they come from.
I listed quite a few doubts, but I think it's best if I posted them one by one to avoid further confusions.
The first one is very simple; so simple that I feel silly asking it:
Where do you put the load on a BJT common-emitter amplifier? Is it (A), (B), (C), or can all of them be the load?
By the way: can the "Rc" (the collector resistor) also symbolize the load?
Thanks for your help...
