Sir at 10:31 you said two points they are 1)If we make Re value high the power supply voltage should also be me made high. 2)If we made Rb value as low the collector-base junction will become reverse biased. Coloud you plz justify above two points?
@youtuberbhai41294 жыл бұрын
I think If we make Rb value low then Ib will increase because Ib = (Vbb-Vbe)/Rb and due to this Ic will reduce because Ie = Ic + Ib due to which Vc will increase because Vc = Vcc - IcRc {Vc is potential at point at collector terminal} due to which Vbc which is reverse bias voltage across J2 will decrease because Vbc = Vb - Vc i.e reverse bias voltage will become less positive. If anyone thinks this is wrong approach kindly correct me. thanks...

4:00 how Ie is nearly equal to Ic They are equal in common base configuration As Ic= (alpha)Ib this equation was proved in solving common bases configuration
@satya_k4 жыл бұрын
Since the base current is negligible compared to Ic and Ie.

Sir if base current decreases there will be less recombination rate ...so if recombination rate decreases there will be more carriers collected at collector region ...so we will have increase in Ic current ...but u said Ic decreases (according to Ic = beta Ib ) which reason should be considered sir....please reply

due to less resistance Rb the reverse bias voltage(Vc-Vb) decreases as Ib is increasing
@niranjangupta30098 жыл бұрын
as you explain increase in collector current will increase voltage drop across emitter and this lead to decrease in base current.... but we know Ie=Ic+Ib.... now Collector and emitter current increase but why base current decrease ... please explain it apart from prove by equation ... mean what exactly happens inside
