Adam I ..... Isn’t that the way learning seems to take place. I too experienced the same feeling from my days (waaaaaay) back in school. I just did not understand why my teachers couldn’t have taught in this way. Even alot of books are hard to learn from because of this......I guess shit happens ....

yea sometimes i wonder , are these college professors really interested in teaching because so many never bother to boil things down into simple form which i thought was the art of teaching. wtf. if they are not capable of doing this then maybe they shouldnt be teachers.

You do awesome videos! Finally found a knowledgeable guy on electronics that doesn't talk weird or obnoxious. Your very clear and easy to understand.

I have watched a lot of instructional videos which use a technique that you also use and I often add my comment " Please use a tripod". My reasoning is mostly to keep me from becoming dizzy or sea sick. I however complement you on a quite steady hand held camera not producing nausea therefore allowing me to focus on your superb, clear, informative content. Thanks for your well done videos. I always learn from you whether or not I am viewing a topic that I think I already know. Another of your 'characteristics' that I appreciate is that you do not waste words using extraneous babble that distracts from the topic. THANKS again. Many of those other videos I can't return to for more information but I come back to yours over and over. Keep them coming!

Hello sir, I am a beginner and I just want to say thanks for the introduction. I have been reading up on op amps and have not gotten it through my head, and most the videos here on youtube make it too complicated and frustrated. this is by far the best video I found on op amps. So thank you and hope you have a wonderful time

I wish I had been able to see this 40 years ago - it would have made a big difference in how I dealt with op-amp circuits!

Pure gold. Somewhere back in my Mims days I got op amps wrong and they've been unduly confusing ever since. Finally I feel straightened out. Thanks!

I have no idea why I found your channel just now.. I have been struggling with OPAMPS and with your clear lectures and actual DESIGN showing what is happening really helped me alot! KEEP UP THE GOOD WORK, YOU, YOU SIR! AND please DO MORE!!!

Currently an EEE undergraduate student; this video really helped me understand how the op-amp circuit works. Thank you very much for your time and effort!!!

Excellent illustration, one of the best OpAmps videos here ever; Thank you !!

I don’t usually comment on videos, but I’ve been looking around for a bit for videos to help me make sense of op amps, and this really did it, thank you so much!

I found this extremely helpful. I needed the physical intuition on how the opamp works and this is exactly what I was looking for. Thank you!

This was one of the best explanations how opamps work. Short and practically useful. The rest shows the data sheet.

this is wonderful how you explain, i'm a physics professor too. for fundamental physics and quantum electronics. great job! I loved the experiment you make it after theory solving

Why does everyone have to over-complicate this stuff, its like they make this stuff hard to learn on purpose. Took me so long to find a good explanation online as to why there is a negative voltage at the output of the inverting amplifier. You explained it well by assuming there is a voltage at (-) and that the output has to go negative in order to make that pin into a virtual ground. Other people have tried explaining it to me by FIRST saying there is a virtual ground and it never made sense to me that way. Thank you so much

You're a talented engineer and teacher. I enjoy watching your videos because you offer a wide variety of topics and knowledge in simple and interesting ways. Thanks a lot.

One of the clearest op amp lesson on youtube! THANK YOU :D

Maybe the Best easiest explanation i've seen on op amps !

I know it's been almost ten years since you posted this video, but it helped me understand things today in 2022. Thank you.

great tutorial, one of the best explanations of the basic operation of op-amps I've seen yet on KZread. A+

This is my favourite EE tutorial video. Your explanations are crystal clear. Thank you so much for making me feel so smart.

This is a difference between a newbie on Monday but expert on Friday,rushing to post a video about something that he slightly licked himself and someone who has a long years indepth knowledge.You have my respect Sir.

This Explanation is spot on!! It saved me hours of time. And we know that Time is money. So this dude saved me a lot of money. Please guys fully view the ads in the video and click on them too, this will support the guy who made this video. Thanks

Hey Alan, Watched several of your videos today trying to knock some of the rust out between my ears. Just recently got my technician ticket and getting the bug again to return to electronics a bit as a hobby again some 30+ years later, so many cool things to play with! You do an awesome job clearly explaining, thanks for all your efforts! Best, - Bill KI7QOA

I'm amping up (pun intended) for my Biomedical Instrumentation final and this was a helpful refresher on some of the basic stuff. You have a very natural, logical and application-based approach to explaining these circuit configurations - it would be AWESOME if you did a few more. Thanks so much!

Your description is better than mine. I have been teaching beginning Op -Amps for 20 years.

Alan. You do a perfect job of explaining it. I like to watch your videos, it has helped me very much in understanding how component's work. Keep up the awesome work.

Finally got to understand how op-amps work with a simple explanation. Keep it up sir.

Nice. One of the best explanations of basic op amp operation that I've ever heard.

Thanks for posting this, we flew through op-amps when I took circuits two years ago and this made everything make sense again. I might actually finish this controls lab now!

Well done, good refresher, being immersed in digital for the last 10 years.

Great tutorial for learning how to step through an op amp circuit! Thanks for the video!

Thank you so very much for this video (and all the other ones too)! I'm just so glad that knowledge doesn't weigh anything, if not I might have to go on a diet... This really helps a lot! (BTW, thanks to you I calibrated my scope probe, it's really cool to know those kind of things you normally don't look into as an amateur). This is a top youtube channel!

Love the way you explained this. Great job. Well done.

Thank you for this teaching.It is so important to understand it before designing with OPAmps

Very very good. You're a great teacher. I really look forward to your uploads. Especially stuff for newbies like me! Keep up the great work!!

Wow - I finally got the "amp" portion of the device name! Yet another great bit of info - THANKS!

One of the best op-amp explanation. Hats off

"This wasn't meant to be a tutorial on how to design op amp circuits" Please do one- you are a great teacher.

Excellent Tutorial showing how to put theory in to practice. I like your choice of circuit as it almost cover everything you need to know on opamps. your results satisfy the formula fully. Vout= -Vin(Rf/Rg)+Vref(R1/R1+R2)(Rf+Rg/Rg) by substituting we get Vout= -4v(20K/10K)+10v(2k2/2k2+2k2)(20k+10k/10k) = 7 Volts which matches your Vout. Thank you and we like to see more tutorials please ! :-)

You are one helluva good teacher. :) I've learned so much watching your videos.

thank you very much for up loading a great video by which the op amp student can gain value able basic knowledge of op amps

Thanks for the informative video! Was able to apply this in comparator circuit for a thermistor controlled fan. Much more sensitive than using a single BJT and easier to adjust.

Awesome video! Very interesting. Hope you keep the op-amp videos coming- Can't wait to see more!

Great video. I learned a tremendous amount about op amps and integrator circuit. Dont fault author on op amp gain think he got idea that is next needed topic. This is a well scripted and executed tutorial that will last a long time in electronic education, not taught as well in ordinary schools!

@9:00 we see the date on your scope: 27-Jan-13. This vid was uploaded the day before that: 26-Jan-13. This shows that you're ahead of your time. Thanks for the excellent video.

It's was very helpful and easy to understand for someone like me who is really a novice. Great stuff!! Thank you.

Thank YOU! Using O-SCope to present what You are talking about is the way this topic should be explained. If you ever have time for more videos about Op-Amps, i will be more then happy to watch it, as for me this are the most difficult EE components to understand.

Darn it, where were you 40 years ago when I was trying to figure this stuff out? =:o}

👍 Thanks for the great explanation.. Today I understood how it maintain both non-invtng and inverting same voltage after watching many videos video about Op-amp and why we feed back... Simple things always makes great..

Great tutorial, I feel like I have struck gold here !...cheers.

Love your videos! You are an excellent teacher sir! 👏

Thanks for another excellent video. Your tutorials are very helpful to me. I would enjoy seeing more about Op-Amps.

my man you know what your doing, i think you just saved my grades

Your videos are always so helpful

Thanks for taking the time to make this video!

Once again, greatly explained, greatly shown, just great, keep it up!!! Personally I am unable to design analog stuff from scratch, but take plenty of circuit bits and pieces from here and there on opamps and anything I can... and put them together to work. With this simple explanation one can at least understand more about what is happening on circuit when opamps are involved. Thanks once more!!

This made op amps make so much more sense I wish I had watched this in school, I never really understood what they did

Wow very interesting analogy! I will keep that in mind. What really got me into circuits was the physical analogies that helped explain them. Like the water analogy etc... so this helps. Thanks.

Great video thank you. You answered some questions I didn't know I had.

You are a gentleman and a scholar.

Very great video sir... I am studying BE-EE now....I am in 2nd Sem. I was bored with OPAMP and its basic.. But after watching this video ..It seems interesting.. Thank You...For such interesting video.

I loved the real life breadboard examples. Great vid

The way you explaining is awesome ...:) and found best of KZread in these. It's my humble request that, it will be very helpful if you can explain how to find the input impedance of op-amp.

Wow amazing explanation man, really made things click a little better for me appreciate it.

This is always good stuff. Thanks for sharing.

One of the considerations for any op amp circuit is the Slew Rate. Many popular Op-Amps have a Slew Rate 0.5 Volts per microsecond. While this may work with audio circuits, it's not a suitable Op Amp for integrators and other math related circuitry. While this video does touch on the basics, characteristics such as latch up can happen with Bipolar Op Amps. I've encountered Op Amp IC's with their tops completely blown away. So without any further discussion, if your interested in Op Amps, there are many good titles to choose from. While You tube can teach and inform you, it's good idea to read about Op Circuits too.

This video is made very good and can be understand easily. Thanks a lot!

Solid explanation! Thank you very much;)

another great video, very good explanation, thanks!

Awesome explanation!

Thank you and it did refresh my mind. In theory this can be solved by superposition. For example replace 10V with ground and now you have output = 4x (- r2/r1) = -8V next put back the 10V and replace 4V with ground, now output = 5 x (1+r2/r1) = 15V add -8V and 15V and you get 7V please note r1 =10K r2 = 20K
