Like all your excellent videos. I have seen this explanation of virtual ground many times, but it is always lacking something. Here the opamp is drawn with a feedback loop, but the huge gain of the open loop opamp is used to explain that the inputs are at virtual ground. Then it turns out that the gain of the opamp with feedback is by several factors smaller than the open loop gain. This would then mean that the inputs are not at virtual ground? Am I missing something in this explanaton. I like to look at it as a differential amplifier with equal bias currents in each branch, so that both inputs have the same voltage.
This vid helped me out a million but lol why you guys always speaking down on the Professors tho….the learning experience is always different went learning at your own pace and time.. Like watching youtube tutorials in the comfort of Your home Versus some huge lecture room with a lecture session that cant be paused or rewind.
the best tutorial on op amps ,presented in a lucid and down to earth manner.loved it. at my age of 61, i have learnt the basics in just one lesson.KEEP it up.
sir yr video on INVERTING OP_AMP IS EXCELLENT AND CLEAR. Yr special aptitude in teaching Is praise worthy. In life many will try to teach but only very few will succeed and you are no.1 amongst them. thanks s.vatsa
I see that the concepts are explained in the description too.. thank u so much sir.. i am a btech student graduating in 2020.. i am preparing for campus placements from your video. Plz do more videos .. hats off👌
Very good RUclips. You are much better than my professor. You make me understand the electronic, my professor just confuses me, maybe it is his job to confuse me
Simply amazing explanation....the total concept is in simply easy way .thank you so much.....but bhaiah "I request you to explain a little bit slow"...
I ‘ve seen ur 2 basic videos of Operational amplifier ..They r really good and I request you to explain by taking some problems asked in competitive exams...Plz
Yes, if you have seen my last videos on op-amp (Integrator and Differentiator), I have taken some examples. And anyway I am going to make a dedicated video on problems based on the op-amp. But before I make that video, I will cover few topics like the gain-bandwidth product, slew rate, CMRR and offset voltages in Op-amp. So, that I can cover a variety of questions based on the op-amp.

Probably a good explanation that would include a differential amplifier with matching, and equal branch currents is too advanced.
I think being 180 degree out of phase and being negative is really different thing. The effect of 180 degree phase shift is the same as negative signal only for sinusidal and some symmetric signals. not all of them.

Wow, now THIS is teaching!
You presented all of this so crystal clear!
My teacher could learn a thing or two (or three) with you!

yea, my teacher really needs to see this video
My teacher learns from this and teaches 🤣. He himself told about that
this man right here is saving lives with these videos.
Too good. I will refer it to all my classmates.
DON'T!!!
Keep it to yu and surprise them 😉
Hehe....you had probably lost trust in most of your friends for keeping this channel as a secret to themselves😂....
Found my Indian guy from youtube.
Thank you, dude. A lot of detail is always awesome to see
Sir u explained the concept pretty well in brief period of time.
In my college we had lecture of 45 min on this which u made me understood in 10 min
you had a lecture.*crying in corner*

Pardon me if I sound rude ,but why did you wanna learn this at 61 years of age?
sir
yr video on INVERTING OP_AMP IS EXCELLENT AND CLEAR. Yr special aptitude in teaching Is praise worthy. In life many will try to teach but only very few will succeed and you are no.1 amongst them.

3yrs ago video, helping me and my bois 3days bfore the exam!🙏
Hope you were our online class lecturer!👀😶❤️
bro i am repeating the same feat as urs let's see how it goes
Explained in a very lucid and interesting manner. Thank you very much sir! You have uplifted the desire of learning electronics in me.
yr video on OP_AMPLIFYER Is WELL thought and executed. the person delivering the lecture/teaching performance Is praise worthy. very clear.

I can't find words to say how good your lectures are sir !!!
I can't see how college professors with so many degrees can't explain the same concept as easily as you do
It's because we don't listen to the professors during class, but are very attentive while watching on yt ( as most of us are here just before exams ).

Hello Amrutha, he had explained this topic in an excellent way....
I really understood it pretty well. Though you shouldn't have used the word "feedback" before defining it. Thanks!
Sir, You are a life-saver.😍 I don't know why my lecturers can't explain like this.😣
Tq very much sir please make more videos like this and help more students to have clear concept and get succeed in life tq so much
The way of your explanation is too good sir.....thank you so much....
Life-saving channel, Thanks a lot
Very good RUclips. You are much better than my professor. You make me understand the electronic, my professor just confuses me, maybe it is his job to confuse me
god bless u brother for providing free lectures
thank you soo soo much you are really becoming one of my favorite youtube teachers.
Very much much much better than my college lectures💯💯💯 Thank you so much❤
Thank you Sir,
I just started in Electronic lab assistant job. It is very informative
My concept is now totally clear.

This was really helpful. I understood the concept clearly.
Thank you very much, it helps me many things. I learned this at school ( and I forgot this) but thanks to your videos, I can understand this better.
You teach better than my profs here at iit
Innovative video. It is very much helpful to understand the op-amp.
Thanks for this very well presented & explained analysis.
Amazingly explained sir...... thankyou 🙏🏻...keep making such videos for us

now how often do you see people making such types of comments on study related videos?
Excellent explanation , really very helpful
my all doubts are gone away......excellent sir...thanku so much...
Excellent vedio with concepts please write the theory in background what you are speaking 🗣️ it will help alot to make notes
Very well Explained. Topic become simple and interesting .
this is so dman good it fells like some iit teacher has taught this
Very well explained... And presentation is also really good. Keep the good work continue 🤘

More than good ❤️
you are the best
Very fine explanation.Thank you so much
Amazing video tho!
Helped me a lot.
Thankyou so much for this. 💪
I can't understand a word of this. Maybe try an accent neutralization course? They're very common and inexpensive.
beautiful teaching
amazing explanation. Thanks a lot.❤
It was a great video.
Superb explanation
these video are very helpful
but I must mention that the opening sound in riduculously irritating
Very easy to understand.
Very well explained....
Gosh that really helps a lot for my class!
Nice..... explanation
Really helpful description.. Thanks 👍
God bless you brother!!
Truly Masterpiece :)
Thank you sir. What happens if we apply negative input to the inverting terminal? Please make video on this also explaining the current directions.
When we apply negative input (e.g -1V), and if the gain is 5 then output would be 5V. ( positive). The direction of current will get reversed.
