First, I read so many different explanations from so many different sources.
I can't understand how it amplifies current and at the same time follow Kirchhoff's Law (Ie=Ib+Ic). I can't understand why would a device that requires 2 batteries to work
be efficient? we could just use these batteries (Vcc and Vbb) for common emmitter model instead of going through much trouble. What does Base do? Does it control current or voltage?
And if Collector's voltage is amplified, why does the law say Ie=.... why not Ic=..... that is what we're after anyway?.
Ok here is what I tried to understand.
Electrons enter Emmitter, forward biased. then meet Base, and some electrons recombine with holes in Base, the rest get sucked by the Vcc, however it is reverse bias between Base and Collector?
I just give up. It doesn't sound as logical to me as FETs do.
Please please I need thorough detailed explanation to this. It is driving me crazy.
