I'm an electrical engineering student from the Philippines and I have decided to watch and study some courses including this, I really don't have the money for donations so I'll just watch all the advertisements that'll appear and recommend NESO Academy to my schoolmates as a token of appreciation, again Thank you so much.
Very nice explanation sir. I'm B.Tech 1st year student from CSE and electronics is a common branch subject. I bunked all the classes of electronics and study from you .your teaching style is awesome.
I am feeling real happiness by hearing each word from NESO Academy. Very pure concepts are dealt here . I can't get better than that!!! Allah aap ko jazai_i_ Khair de Sir. Thankuuuuuuuuu so much....
It would be very helpful if you could make a pdf , explaining the concepts so that we can access it even in offline. It would be appreciated if you can create a cheat sheet of formulas and important points at the end of that pdf .
Very good lecture on transistor baising , particular the idea behind the use of transistor and the reason it is used for, and explaination of reverse saturation current was too good , nicely presented .
AWESOME TEACHING SIR..Thankyou very much sir...thanks for teaching low resistance and high resistance region of transistor ,and amplication of transistor...thank alot..it means alot to me sir...
@ 5:30, why are the barrier potentials at both junctions the same knowing the difference in the concentration difference? btw, really good work done by you sir.
7:51 - Can you please explain why the few free electrons that come from the E and recombine in the B move as valence electrons through the Base Terminal? Like, what happens when they recombine that makes them flow through the base instead of passing on to the Collector Region?
There are not alot holes in Base so some are recombined but there are extra electrons that are left from the recombination so they will move to the collector This is because base is small and light
At the moment you said v=> k.e., that the electrons flowing due to Vbe have a high velocity, and therefore high kinetic energy, I finally understood the *reason* why the emitter can submit electrons to the collector in the majority (rather than them landing only in the base). Thank you very much for this video. Just to check my understanding... is it true that are we able to modulate the electron drift velocity by providing an electric field from Vbe, which, in turn, propels the electron through the P region?
This is really shocking for me to see that, there is only 0.8M views. why? It should be more than 30M views!!! They are very discipline in Teaching Mode.
Arent electrons travelling from the emitter to the base minority carriers in the base? If so, why do we use alpha Ie to represent its current rather than using Ico?
I had a small doubt.it is said that the collector -base junction is reverse biased therefore the electrons entering the base from the emitter experiences more resistance from the collector base junction and they should leave the transistor from the base terminal.no?but why it is not happening ?
10:46 sir in my book, it is drawn reverse. ( you have been drawn from up to down but, in the book they have given down to up and the base current is drawn from up to down ) sir, please clarify my doubt ...???
sir acc to some books base region is more doped than collector region and the reason given in that is in active mode if the base is lightly doped then depltion region will shift tk base side thus deplete the whole base since its narrow so the collector is the lighest doped do the depltion width will be across the collector side is this is right?

Love from India 💕
Now what you doing bro. I hope you will have a bright future
now that's how you repay those who helped you 😁 nice bro
who asked ?
OH my god.. You are awsome... I can't believe this video is from 2016 and in 2024 it's still so amazing....
These lectures teach me more electronics than my college
Thank you so much for making them! They're so good
same here😁
In india we study this in class 12

I appreciate NESO academy for providing good video lectures on Analog Electronics.
This was the best lecture about transistors that I saw on TH-cam that's what I wanted. Thank you.
I am feeling real happiness by hearing each word from NESO Academy.
Very pure concepts are dealt here .
I can't get better than that!!!

They deserve❤

The notation for the cell used must be VsubBE thather than VsubEB as B is posetive relative to E for an npn transistor, also, really well explainned.
Thank u so much for the clarification.
Best education channel on TH-cam
Wow, I just stumbled upon your channel and it just blew my mind. Legendary!
best electronic lectures Ive seen so far, many thanks
Hello sir,your presentation is excellent on Analog electronics.So far I referred up to clippers,clamppers,voltage multipliers from S.C
The way you teach is fantastic..Hopefully our college teacher would teach like you..
forgot some basics so came here to brush it up, really good video
Very good lecture on transistor baising , particular the idea behind the use of transistor and the reason it is used for, and explaination of reverse saturation current was too good , nicely presented .
This is the best video for transistor operation
100% better than my clg.. Loved it sir. ❤
This really help me understand PN Junction and also BJT!! Great lecture!
AWESOME TEACHING SIR..Thankyou very much sir...thanks for teaching low resistance and high resistance region of transistor ,and amplication of transistor...thank alot..it means alot to me sir...
Damn my concepts are now crystal clear !
Keep appearing in my feeds neeso, subbed already :)
@ 5:30, why are the barrier potentials at both junctions the same knowing the difference in the concentration difference?
btw, really good work done by you sir.
my sir literally took a 2hrs of class to explain this 😂 but bro u just nailed it thank u 😻😍
Worth watching
Best video with best explanation
it is a good video explaining the basics of BJT. Nicely explained and also cleared the doubt.
thank you
Salaam. Alhamdulillah I am in love with this group! Nice teaching! Carry on.
Btw it will b Vbe not Veb
Excellent Explanation. 👍🏻
Beautifully explained and presented ....... ......
Helpful for my semester exams 3 hours from now
2 hrs 16 mins from now
9 hours from now
Now
Now 😮
hope u doing well mate, its been 6years you commented
loved your videos these are helping me a lot during exams plzz continue...in the same way
one of the best explaination ever received
I love you neso
At 5:15why both the junctions has same barrier potential as one is FB and other is RB.
Because there is no biasing...
Excellent explanation about working of Transistors Thank you Sir
understood BJT first time in such a nice way
life saver video........... last day of exam
Amazing teaching. Thanks a Ton.
THE MOST DETAILED EXPLANATION YOU WILL EVER FIND FOR THIS TOPICCCCCCCCCCCCCCCCCCCC

They are very discipline in Teaching Mode.
Excellent work 👏
I have no word tho thank you .....you helped me so much thanks !!!!!!!!
very good education. thank you so much.
BIG DOUBT PLS ANSWER at 7:15 how did electron hole recombination in base cause e- to move to Veb.
I think holes are positive and electrons are negative so they recombine
at 3:05 How can the Input Voltage Vi be smaller than the Output Voltage Vo in which we have a higher resistance R in Vo???
Having current constant, according to ohm's law voltage is proportional to resistance(v=ir)
thanks for creating this video
you're a saviour
Hi...Please upload all the Analog Videos as much as possible...I'm preparing for exams and ur videos are so much useful
Why is the net voltage V_e-V_EB? Isn't the positive of barrier potential at the n side?
good site, please keep the fire burning .thanks a lot
very helpful presentation. thank you
Please give presentation on Series voltage regulator and shunt voltage regulator too in Analog electronics.Those are very useful for students.
Thank you...
for giving such a lecture...😊😊
thank u so much it was very difficult for me to understand from those words in a book u made it easy..
Since there are two junctions, shouldn't there be two barrier potentials instead of same Vb for both junctions during the open circuit condition?
excellent lecture about transistor
Well explained
thanks for this very nice presentation
U talked about breakdown of transistor in terms KE of e-'s in one video can't find it out plz provide the link
Thank you so much sir ❤super explanation...
thanks sir.....great video.....☺️☺️
Your presentation is good on BJT.
Thank you for your explain , it's useful for me
thank you for your explanation
Sir then what happens to junction. 2 will it not stop the e- from base as give reverse bias to cb junction.
Why barrier potential is same for both junctions as there is a difference of concentration at both J?
Arent electrons travelling from the emitter to the base minority carriers in the base? If so, why do we use alpha Ie to represent its current rather than using Ico?
Thank you sir ❤️
How are both the junction voltages equal?
Thx vedio was helpfull to me because i have exam tommrow.....
Where was Neso Academy during my semesters? :( Getting a lot of help for my interviews though :)
how do forward baising and reverse biasing lead to the increase and decrease of the knee voltage....
Great explanation (Y) Thanks!
this video is very helpful for me Thankk you
if the resistance is high at the out put terminal if tends to low current then how the signal is amplified
Please explain (1-alpha)N! Could not get that point? What is 1 doing here?
What is the value of Ic in pnp transistor in terms of alpha and Ico
Super voice and explanation
Thanks for amazing lecture and explanation. Can you add lecture video for IGBT?
Sir u rocked . Luv u .
great lecture....thank you
4:33 ,sir why N is connected to +ve terminal, it should be connected to -ve terminal,,since its NPN transistor..
Reverse bias in collector base junction
nice video full of helpfull stuff thank you
I had a small doubt.it is said that the collector -base junction is reverse biased therefore the electrons entering the base from the emitter experiences more resistance from the collector base junction and they should leave the transistor from the base terminal.no?but why it is not happening ?

At 8:47 u said j1 and j2 ,both are forward biased but in previous lecture, you said in active mode j1 is f.b. and j2 is r.b.
Sir plzzz explain
Really a very very helpful 🥰🥰🥰🥰
tq teachers from this video i learned correctly thanks alot
