Hello everyone, there are somethings that i dont understand in this BJT circuit http://prntscr.com/4kx1ub
first thing to notice is that the way i see it the current that goes down the Rc resistance is IC+IB this sum gives us the IE current so i suppose they are the same, arent they ?
After that i made some sort of analysis here http://prntscr.com/4kx3vm (when i write f.o. i actually mean f.a )
The reason i bother myself with that circuit is that it is not dependent by temperature --> B (beta)
we know that α( alpha) =(B+1)/B which we can say that is a bit less than 1. but we still have that RB/B factor, how do we solve that confusion ? Thanks in advance
