BJT transistor analysis: common emitter confusion

[QUOTE="Jony130, post: 5553960, member: 381547"] Notice that Rc resistor and DC collector voltage (Vcc) will limit the maximum current that can flow in collector. The maximum collector that can flow in this circuit is [B]Ic_max = 9V/330Ω = 0.027A = 27mA. [/B] So in this case the BJT is in saturation region and [B]Ic = β * Ib [/B]do not hold anymore[B]. [/B] The BJT is just like a water tap. What is happening is that the base current is [B]"[/B]controlling" the amount of current that Vcc supplies (can supply). Try increase in simulation Vcc voltage (2000V) or reduce Rc resistor value or increase the RB value . [/QUOTE]
