The classes given by the neso academy is very basic..hence ..an advantage for all students of different types to grasp things and learn it faster....these classes are really awesome and amazing...i liked this..thankyou so much
Simplicity in teaching is maybe the most important thing.Some people are teaching it with chaos on the screen. I get tired when watching some videos of others.But your screen does look simple,clear, with a beautiful writing but also full of useful knowledge. Thank you!
No words to explain how super ur lectures are..really amazing.very useful to basic learners and graduated ones. Thanks for serving with such kind of videos.
Good presentation. 👍 I'm refreshing my theory after decades. The only thing I found difficult was I, as an American, have a bit of difficulty understanding him. Thanks.
guys seeing so old comments like 4-5 yrs old, i wonder what they are doing in their lives now...can anyone reply to my comment after maybe 5 years so that I can revisit my this thought and judge how far have I come, if I was able to fulfil my 5 yr old self's expectation's in life or not. Thanks, right now I have to go prepare for my college midsems lol
it would be very helpful if you can number you lecture .. so we can what we can see after the one we are watching .. by the way nice teaching ..helped me a lot .. thanks
SIR Just now i watched yr video on DC BIASING, LOAD LINE AND OPERATING POINT OF TRANSISTORS. Yr above video is inspiring. As i have come across in my experience, even many a B.E/ME graduates are unable to understand them properly, how nicely and convincingly u explain so well with such a ease and clarity that too with out the least confusion is amazing. You earned my highest respect, appreciation as well as my envy of your sound knowledge. while i have now understood many an important explanation u explained there still i have to grasp some few points being a slow learner. So i have recorded in my mobile and need to go thro them repeatedly. Yr video is outstanding. How i wish the speaking volume a little louder. Thanking you vatsa Bangalore India
Really your videos are very approachable.....I didn't understand electronics .....But now I have a clear understanding...After watching these videos....Thanks a lot.
Ive have for a long time now considered the possibility of utilising methods not known to current science.. I started to think outside the box and one of the first questions to arise was, does information have a physical weight? I.E if a hard drive has a maximum amount of data stored on it, does it weigh more then it did without data stored to the device.. The answer is no because machines operate using transistor switches to sequence binary code and gate positions are either opened or closed therefore no physical weight is added. This was a very significant question in that position sequencing determined overall machine performance and the fact that a program could actually be written to carry out virtual switch sequencing via software without it physically closing switches on the intergrated circuit led me to believe that I had just solved the issue of heat displacement in silicon based processors. If the transistors are all opened and utilised by the software they generate no heat from being open and closed but instead the software progam recreates binary gate functions via cloud computation and a virtual engine opens and closes the gates. My Hope is that someone takes this and changes the world. GM.
Neso Academy make videos on transistor at high frequency and fet small signal models dey r also.very imp. topics and also on single stage amplifiers of mosfet dey r very significant topics dont mis dem i cheked out for dem whole semester
really nice video , i have a quastion that at15:53 wouldnt the broan signal drawn below the graph have a large amplitude upto the complete corners ? actually my sir wants a pictorially perfect graph for my exam so i was confused on this
11:00 when Uce=0, Ic=0 according to transistor output characteristics graph, but Ic=Vcc/Rc according to output loadline. Can anyone explain that to me?
If the input voltage i.e. Vbe is sinusoidal then he have just drawn the voltage graph here. For simplification just rotate the graph and see the voltage graph
Sir at 14:53 minutes you explained the importance selecting the operation point. But you said clipping in terms of voltage for a positive half cycle(when Q1 is selected) while the clipping in terms of current for a negative half cycle(when Q2 is selected). Can you explain both the things in same point of view i.e., either voltage or current? Because if the current is zero means it doesn't mean the voltage is zero. And I also want to know whether the waveform you have plotted is current or voltage waveform. If you have plotted both as different waveforms means you could explain the thing in terms of power.
Both waveforms are output voltage waveforms, but he explained Q2 load line with respect to current because it is where the active region ends. And if you go beyond that voltage, the saturation region begins. I figured this out so far, I'd appreciate to share your thoughts. :)
Q point is corresponding to the IBq(base current) which we got from the VBE vs IB graph. Suppose IBQ= 2 microamp then at Ic value 2 microamp we will get our Q point.
excuse me sir i have a doubt... 8:14 you said if we increase 'Vce' curve will shift toward right. How exactly can we vary Vce?? isnt that the amplifed/output voltage? i mean how can we vary it? what is the process of varying 'Vce' Kindly answer it sir :)
Sir, in output characteristics you said that by increasing base current ( IB) we can increase collector current(Ic) and this also serves the purpose of current amplification for which CE Config is made for. But sir my ques is that ideally base current should be zero because larger base current means larger recombination taking place which is not supposed to be the case. So why are we increasing Base current here to get more amplification.Please clarify these two contradictions.

U r unbelievable 😘
Neso academy is a real boon. Ur explanation is fantastic. Please make such great lectures
Those who can explain a newbie and if he/she understood then he is the master of the topic,Neso my master

what would I do without your help! Thank you
From 15:15 can any body explain how he drawad waves
If the input voltage i.e. Vbe is sinusoidal then he have just drawn the voltage graph here. For simplification just rotate the graph and see the voltage graph
maybe i ain't gonna pass this sub without u

Thank you sir...it helping us really...
Really helped me for quick revision , Thanks a lot
Thank a lot your teaching are touching
brilliant teacher
Thank you sir ❤️
At 10:44, im still confused of how to get the Q point. Why did you consider that particular point?
Q point is corresponding to the IBq(base current) which we got from the VBE vs IB graph. Suppose IBQ= 2 microamp then at Ic value 2 microamp we will get our Q point.
THANK YOU SO MUCH. You helped me a lot
At 8:15: If you increase the output voltage won't the line shift to the left?
Bro your video really help me thank you
super lecture thank u very much for neso academy
Thank you very much for the lecture. Really good.
tq man for clarifying doubts
Thank you sir....it's very usefull for me
How to draw the output wave form
At 9:45 how can you say it's-Vce how's did you identify it's voltage drop
excuse me sir i have a doubt...
8:14 you said if we increase 'Vce' curve will shift toward right. How exactly can we vary Vce?? isnt that the amplifed/output voltage?
i mean how can we vary it? what is the process of varying 'Vce'
Kindly answer it sir :)
Thanks very much for this video it's really helpfull
thank you sir very clear explanation
I have a doubt, why does the waveform get clipped at maximum value of current?
Cuz the positive half cycle of the waveform enters the saturation region which distorts the signal, thus clipping taking place
@@AS-nx9fu my engineering is over but thanks anyways XD

But sir my ques is that ideally base current should be zero because larger base current means larger recombination taking place which is not supposed to be the case. So why are we increasing Base current here to get more amplification.Please clarify these two contradictions.
i think clearly sir has told that base current has effect on Q value while Q value has no such relation with collector current
Sir will u please lecture a video on "why do we need biasing in transistor"
