Lets take a simple BJR transistor having an Rc. The Ic = beta*Ib, of course. But Ic=(Vcc-Vce)/Rc as well right? Now the confusion, does Ib cause Ic or is Ib possible without Ic (and thus no Vcc)? If we have Vcc and thus Vce than we shall have Ic thus we can have Ib=Ic/beta? What causes Vce, is it Ib or Ic. The books don't go into these other perspectives. I can see the equations and that is what is making me confused. I am confused, where does the process start from... Why does Vce vary when we put in a signal?
