Seriously bro.. Great job..😎 I never wrote a review for any video but you deserve it.. 👍

How Ie=Ic in the output loop KVL but this is not the case in the input loop KVL where you used Ie=Ic+Ib

[@adi_reigns3470]

Ib is very small

[@snappywho666]

@@adi_reigns3470 how do you know it is very small?

[@amankumargiri3163]

@@snappywho666 coz of its low doping

[@jatinkhajuria7151]

Ib is measured in micro Amps

[@satya_k]

@@snappywho666 Because most of the electrons that emitter emits is collected by collector and almost no electron goes into the base region that's why base current remains very very low

[@venkateshanantapalli4343]

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?

[@youtuberbhai4129]

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...

What board do you use to write? It's the best electronics I've seen

[@niranjangupta3009]

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

[@bhu1334]

As voltage drop across Re increases there is less voltage across Rb therefor Ib decreases

[@amankumargiri3163]

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_k]

Since the base current is negligible compared to Ic and Ie.

[@hanishgopi]

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

during different bias circuit explanation sometimes Ic = B.Ib sometimes Ic = B. Ic + (B+1) Icbo what are you the conditions and scenarios for the choice?

[@gaurav3794]

Icbo is generally way smaller than Ib. So, we can ignore it if we want.

[@mohd.rajeen4256]

at 10:27 can someone explain how taking very small resistance Rb will reduce reverse bias at collector-base junction??

[@BADASSBLADE]

due to less resistance Rb the reverse bias voltage(Vc-Vb) decreases as Ib is increasing

best for understanding.

superb lecture

[@poojaraval1078]

thank you soooo much sir : ) i thought it is quite difficult to understand

[@farheenwaqar7880]

why your concepts in this video are so much different than Thomas L. Floyd (Electronic Devices)? why there aren't 2 biasing potentials Vcc and Vee and the base is grounded?

[@dellavincent8300]

Yeah....that's wat I was thinking! Emitter should be biased. Rit?

[@PintuKumar-yo8vq]

how (Ie=Ic) in emitter bias configuration

[@satyam1945]

Pintu Kumar yeah might depend upon rb....if we consider Ie=ic+ib from output loop and also see input look so very much some assumption have been taken too....for ic=ie

[@wheniambored3903]

thank you for just just wonderful and interesting lecture ,sir i have seen in book "introductory electronic devices and circuits " by robert T.paynter ,,he used two supply in emitter bias configuration one is Vcc and other is Vee,,and you have used only one supply which is Vcc,,sir please elaborate?

[@macwaysmayank8070]

It is derived from vcc only . So u can use vcc alone . It's ok u can go for any 1 of the both

[@AlessandroBoggiano]

Can someone, please, explain why (10:17), low RB takes to reduce the CB junction ?

[@syedmuidalkais5756]

Because of low value of RB, voltage drop across RB will be less. Potential VB will be more. Reverse bias voltage, (VC-VB) will be less.

[@santosh-mb5wc]

Plz also tell How Ie=Ic (we neglect ib) in the output loop KVL but this is not the case in the input loop KVL Ie=Ic+Ib ?
