Dear professor. I appreciate you posting these. Out of the many videos I have watched on this topic, your patient presentation is among the best and easy to understand and absorb. Your presentation style, where you wait for the students to answer necessary fundamentals questions, is a good way of presenting. Many other videos and lectures on these topics JUST FLY past these fundamental questions. At which time someone like me GETS STUCK and then shuts down and loses confidence. As you were asking these questions and waiting for an answer, I was answering the questions out loud as if I were there. I will look to your videos for any topics I need a good lecture on. And at my university, my professor gave these same examples during lecture, and they FLEW RIGHT OVER MY HEAD! It is nice to have someone that "can speak my language." Thank you. And if you still record lectures in this format, please keep posting.
Correction, it is indeed Electrical and not electronics. Electronics involves the components of intricate systems with in a device like for example an iPhone. Basic circuit / electrical theory like this is actually Electrical Engineering* I know this to be the case because the associate dean of my engineering department spent and hour telling us the difference between Electronics and Electrical ahahah.
Thank you very much. You really saved my neck. You make my electricals classes much much simple and easy. Your videos may seem long but it feels like I'm watching a 1 minute full on lecture and able to absorb so much. Thanks.
Thank you so much for taking the time to make and post these videos. I can tell that you really try to convey the information clearly and concisely so that your students can really grasp the concepts. The world needs more teachers like you. I am in your debt.
..awesome tutorials !! after years of struggling to simply OpAmps to understanding level...he has made me see the Light...forever grateful...highly recommended..~~
The reason for the voltage follower is to isolate the connection between the voltage source to the output load: the source voltage sees an infinite input impedance and the load sees zero output impedance which is ideal when connecting one circuit to the next......this is also the reason to call this circuit a "Buffer".
Professor, your videos are amazing! However, because I want more students to come and watch your videos, I suggest that you give each example a TITLE. for example, before you do the inverting amp, title the example "inverting amplifier" because most students come to watch specific material and they might watch the example and not even know that it's what they need to know for class! thank you so much again for posting the videos!
V-=V+, remember? And V-=V+=Vin. So, the left terminal of the resistor R connected to the ground and the right terminal of the resistor R connected to Vin. So, here is your current flowing.
Preciso de um e ou , baixa potência, três circuitos independentes cada um SÓ com seus 2 ou mais amplificadores operacionais, em Classe D, com fonte SIMÉTRICA comum, circuitos quase iguais e SÓ sintonizados na entrada de áudio. Veja que não é SÓ Pré ou SÓ Equalizador. É bem simples, mas é e sem potenciômetros nas tonalidades. Por favor. Muito obrigado.
If an ideal op amp has infinite resistance there, but real life cannot mimic it, why don't they just make it an open circuit? Is it in actuality necessary for some current to flow there?

in last question, why v+=v2 [R÷(R+R)] please HELP😢
You are the kind of people who makes me fall in love in Electrical engineering , Thank god you exists .
Abdullah Gharaibeh its electronics bro

Prof Zahi Haddad is amazing! Very chronological, detailed oriented and HE KNOWS HOW TO TEACH!
If I once get my degree, I would give that to you. You are the best teacher in electronics I ever had! I mean it!!!

this one just cleared my hardships in op-amp...thanks a lot for making it easier
Every high school student aspiring o be an engineer owes it to themselves to get a leg up and watch these videos.
Thanks for posting video. Made me realize that it's just a voltage divider at top when doing a negative feedback based setup.
TOP. The best is the web, regarding Op-Amp. Very concise and the way it is presented is amazing. Hope you continue the same way for others lessons.
Simply the best of op amps, finally got it!!
This is a great video. At 15:54, great way to make me understand the purpose of these!

חדד.. אתה אלוף העולם! Thank you
Thanks a lot. Your explanation is very clear and helpful.
You make me proud to be an engineer.

thank you so much again for posting the videos!
Funny, I was thinking the exact same thing, even before reading your comment
wow amazing..superb teacher. perfect concepts.
Great video thanks for explaining the concepts easily and clearly
İngilizcem olmamasına rağmen anladım bu adamı bizim ülkeye almak lazım.
Thank you so much, with love from Israel!
i love the way of your teaching sir zahi
Thank you so much, seriously it was very helpful.
May u live long..,
🙏🙏🙏🙏🙏
with love from India..

what?

That voltage followed seems weird. Wouldn't a capacitor be a better power on/off transition element to smooth out the otherwise square pulse wave?
The best teacher ever May Allah bless u
Nice one ☝️
BIG LIKE! Very helpful video.
I like your teaching. it is really helpful.
Will someone give this guy a medal
amazing man ............
best explanation of opamp on RUclips so far
Thank you for the great video
thnx so much sir, seriously it was very helpful.
May u live long..
Cool stuff.
Great Professor!
Thank you Sir. Great lesson.... V useful....appreciated.
Very good lecture
Explained well sir.
I like you lectures, the only thing I don't like was the explanation of the buffer.
Everything else... perfect.
Thanks
Great as always.
If that’s the case “we got it made” lol epic
And to think no professor explains it as simple and matter fact as that.
You are awesome thanks man
Videos are very helpful. Thank you !!!
very nice and helpful
Thanks for posting this video!
Great lecturer
you are a legend
dear professor can u also make a vid on diodes please!! specifically determining if dey are on or off and also function generator using zener diode
Thank you sir :) Extremely good explanation.
hey zahi! i m from india..vid helps me lot
If the voltage in v- and v+ is same, so how can they be used as a comparator?
i think thats really interesting 😊😊😊😀
the main purpose of a voltage follower is to drive a low impedance input with a high impedance output
Wow! Wish you were my teacher in college!
Love u❤️
Sir please throw some light on phase error on op amp when ac signal is fed to both inverting and non inverting trminals. Thanks
thanks sir. i like your lectures.
so super
Great tutorial! Thanks~~
for noninverting amp, i don know why the current I1 flows at the resister R linked ground . please explain the reason
V-=V+, remember? And V-=V+=Vin. So, the left terminal of the resistor R connected to the ground and the right terminal of the resistor R connected to Vin. So, here is your current flowing.
very helpful
someone please tell me how those equations even make sense at 13:40 (except for the first one)

Life saver
Thank you !
I want to cry, I really can't understand my circuit subject. 😭😭😭
If an ideal op amp has infinite resistance there, but real life cannot mimic it, why don't they just make it an open circuit? Is it in actuality necessary for some current to flow there?
I'd really like to know the answer to your question (@RinRin) as well.
I love you from the bottom of my heart
thank you very much sir
15:56 How TF there is current when you just attached it to the ground????
best lec
thanks professor
helpful
Is there an e-mail id at which I can contact the professor
yeah inverting amp are use in sign changer
thanks a lot
i love you.
best !!
nice video....
but please improve the video quality
we cannot see the equations and notations....
Thank you .....
thank u sir
43:35 there i hear some apple being cut xD
thanks sir
non-native english speaker here: does anybody know what sib, sibb or sip mean? (see: 10:30) R sib 1?
R sib 1 is the same thing as R_1 which is a subscript.
this guy sounds like conor mcgregor 30:50
Can I have your mail, I have an exercice and I want your help with detail please advice
E então.
ap amp :)
very helpful
