You deserve all of my tuition. You alone taught me Organic chemistry, Calculus, Physics, and now circuit analysis. These universities are next to worthless, I am sorry I cant support your videos more (financially). Half or my professors couldn`t even solve the problems they assigned when I went to their office hours.

For years now, every time I watch one of your videos, a complex topic becomes accessible. You are one of the great teachers of our time. Wondrous!
Your channel is Organic Chemistry Tutor, but I'm an electronics student and learn regularly from you. You explain better than my electronics lecturer.
I am in my Masters. Just so you know this guy is also helping Masters student with their work. Appreciate this so much

The moment i saw this video on my search list, i knew Immediately that its done, I'm understanding these things.
Amazing explanation, perfect pace, perfect examples, perfect voice. Couldn't have been better made! Subscribed, liked and added to playlist; thank you!
Your voice never changes , I love it!!
Op-amps? More like props, man! These videos are so amazing, and I'm so thankful that you made them and shared them.
I'm doing a triple major in chem, compsci, and math. This man has saved me in all three of those majors. I found you in grade 11 and you've literally saved me since.
this teacher is so very good and he has help me alot in my electronics and other engineering courses! you deserves donation
I've been your fan since 400k subs brother...You've gotten me through every course..thanks
You deserve some sort of global award for your contributions to humanity
Dude this video is more useful than my prof rambling on for the whole semester. You’re literally the best

Finally !! Someone who's explained this to me and I understand. Thank you !! I like the form of your graphics. I subscribed. I'm an eng with budding interest in electronics. Cheers
Thanks so much! This really helped build on other videos I'd seen that didn't get quite into the examples but were more theory based
just from a lecture..caught it late was not understandig anything and here iam now undrstanding everything
I think that the conclusion of all your heroic work is obvious. If one masters chemistry, there nothing in the universe he can't master. Thanks for all Champ !
you have made my study so easy and effective. God bless you abundantly
Bonjour, First time i understand feedback since years . very well explained. Thank you very much
Bro how do you have a video for literally every topic I've ever had trouble with
I'm your fan This explanation is superb as your all videos And could you pls talk about the transistors.........
A very accurate, well paced educational series of videos.
Im nearing the end of the semester. We started this lesson today. Im trying to study this over the weekend. Thank you for all of your great videos
I have been doing this in my course for 2 weeks now and I have not understood anything about this. Now in just 12 short minutes you have made me understand it completely thank you so much!
I remember when i watched this video to learn this when i was a EE freshmen in college at Oregon State. I am now watching it to review it as a senior at Oregon State. Thanks OGCT.
Amazing, you made it easy to understand👌... thanks man!
Exam in 25 minutes rip 30%
How have you not received a Noble Prize. You've Taught me many topics, you are literally my lecturer... Thanks
Your videos are just great! I can not thank you enough!
!!! Will be having this exam after tomorrow!
This is a very comprehensive video. Thanks for making it.
I don’t know what is this about but I like your voice is very pleasing
Thank you Sir😊 In the inverting amplifier circuit, the method to eliminate the output error voltage caused by the bias current is to connect an R to the ground at the non-inverting input terminal. The value of this R is: R=Rin//Rf
I had to take a second look at your subscriber count, 4.66 million, well deserved. Found this channel back when it had 250k

Nice vid thanks for the tip
BRO how do you know all this?!?!?! You've carried me through most of my classes in HS and college!!!
You should include ideal cases and how to solve with missing variables using node voltage method in another video!

I got a final this Tuesday on industrial electric
some professors might have a doctorate or PhD, but that doesn't mean they can teach. thank you for your videos.
You use them as gain amps, mux, rectifiers, diff amps, buffer, regulated supplies, balanced drivers, instrumentation amps, dc servos, and many more applications.
You're God sent to me
Potentially daft question... but if you didn't have access to the "middle" of the 2 batteries to use that as a ground for the op amp, could you put in an equal resistor voltage divider in parallel to the battery, then use the point in between the resistors as the ground for the op amp instead? Sorry if that's a dumb question.
excellent super bro
Thanks
man, how come you know everything
Thanks, please produce more related KZread. You are much, much better than my stupid professor. You can make me understand the concept, but my professor just confuse me, I think confusing is my professor "s job
Hi! Could you discuss about averaging amplifier as well?🥺
Good
In the example, is the gain 20 or 20k? Should the output voltage not be 200V instead of 200mV? Thanks
So, in your first inverted example, why is the value of "R" what it is. How is the circuit affected if "R" is increased or if it is removed and the "+" pin tied to gnd?
Is there a best practice way of making a non-inverting uni-gain setup?
I'm really really curious to know how come you know so much.. I'm dying to hear the story and learn from it
Does the phase change even if the amp is powered between 0 - and a +ve voltage ?
HEY PLSSS more videoz about ece Coursw
8:25 the non inverting input terminal doesn't need some resistor?
I have a question guys, how pin 8 which is a not connected pin is used in mobile phone detector ? (CA3130)
This dude is a gud dumn Hero😮
nice video. But one remark: @11:53 (continued), the output should be between -200mV and +200mV because it is an opamp in inverting mode. :)
@PunmasterSTP
2 жыл бұрын
I would think it's still correct and reasonable to give the range as +200 to -200 mV if you usually specify the maximum voltage before the minimum voltage. Is there a convention related to op amps where you would specify the minimum voltage first if you're working with an op amp in inverting mode?

so the feedback resistor is always connected to the inverting input ?
@PunmasterSTP
2 жыл бұрын
I think that must usually be the case, because I think if you were to connect it to the non-inverting input, then you would get *positive* feedback and the signal would grow without limit (until it reached the supply voltages).
Why does Rin not connect to V+ input port for non-invering op amp? Why does RF not connect between V+ and Vout?
Op amp is like differential equation
Could anyone please say what will be the gain formula if input is applied through a resistor in non-inverting terminal and output is connected to the non-inverting through a resistor?
hello mn rất vui được gặp mọi người
He showed how to connect the batteries and the circuit diagram, but it would be nice if that was immediately followed by a hypothetical output. I mean, what good is it to see the circuit if we don't know what it actually does? He gives an example at the end, but it would be nice to have it after each diagram.
Please anyone explain what is the use of inverting output and non inverting output and when we need it ?
I have a dumb question: why are Rin and RF in parallel
I can't wait until I start my career so I can support this man's retirement.
Im watching this 1 hour before my exam in the bus
Why do you have to add 1 though? This is kind of a random question but if you do know why, please tell me thanks!
