Excellent and neat Explanation . My Universitary Teacher was absolutely UNABLE to break down for us the concept of amplifiers and its variants. Thanks a Lot Sir You saved me !
At that point you don't know whether you'll end up multiplying that expression by by A later on. It's not always safe to do the approximation until the end.
Those videos helped me understand how to work with those, but we do things differently and our technique is easier. since (v+ - v-) = 0 and v+ = 0, that means v- = 0. That would make things much easier
This could be solved in a much easier step: we know from an Ideal amp that V- = 0 so therefore every where there there is V- substitute with 0. And then just cross multiply to get Vnot. Ganz einfachhh(german (: )
It confuses me why you say the gain is huge, then proceed to say the gain of the circuit is the ratio of the resistors, which could be anything even a small ratio, otherwise good explanation :)
Multiplying to a fraction only multiplies numerators together, and denominators together. A is only a numerator (with denominator technically 1), so it must be only multiplied to the top.
ok ok... wait... i am going for some popcorn... this is my covid19 movie fix...:/ while waiting for wonderwoman and 007 to come out... Mmm, they should make a movie together...:) thanks
Can't you just cross out V- since in an ideal op-amp V- = V+ and V+ is already confirmed to be zero, so V- would also be zero. That would eliminate a lot of steps...

Let's change color so we won't get bored; What a true legend...
10:40 removing half of the formula makes it really satisfying. idk why :D
Very clear video! But unnecessarily lengthy.
아저씨 덕분에 시험문제 풀고감 감사감사. thank you.
Great explanation for inverting op-amp circuit basics.
Nice. Though it seems asserting that (Vo/A)=0 around 6:09 would cut calculations in half
that is just what I was thinnking

I believe its because he said that he was going to do it the hard way with all the algebra in case someone doesn't understand if he skips steps.
Suspect42 Yes it is. Standard calculus.
He chose to make life complicated lol
Very clear explanation!
I finally understood🤣
Do you have other electronics tutorials or a playlist?
Thank you!
great explanation
Thank you for this video! very helpful.
Thanku

Why can't we see r1 and r2 as a voltage divider?
Where is the real word example?

where is the video with easy way
Very nice to hear your voice! Could you tell something about Input Offset Voltage of an Opamp PLS
Gerard Buurman
You should write as Vout...
Since you wrote Vo, it is confused with V0...
can you explain the inverting op amp in the easy method ?
it is explained in the virtual ground video
dear please check this. I hope it will help u ruclips.net/video/NY0xD0wVTkc/видео.html
No it's not !!
Thanks Norm MacDonald
at 4.10 you substitute (V-)-(Vo) for VR2. I don't understand how.
Voltages across R1 and R2, based on the direction of i, so the voltage across R2 is VR2= (v-) - (Vo)
It confuses me why you say the gain is huge, then proceed to say the gain of the circuit is the ratio of the resistors, which could be anything even a small ratio, otherwise good explanation :)
why is V+ =0 (2:14)
where is the denominator 'A' while taking LCM before grouping terms of v0 and vin
Latha P.K both equation seperated by equal sign will have A as denuminator so you can just cancel them out
if you multiply the top with A don't you need to do the same to the bottom? 6:34
He multiply both terms.
Multiplying to a fraction only multiplies numerators together, and denominators together. A is only a numerator (with denominator technically 1), so it must be only multiplied to the top.
So awesome I can view this 144p
Does a negative voltage imply that the current is going to the op-amp on the output?
it means there's a 180 phase shift between the input and the output

flightlesssky you cant cance out zero to a zero its just like multiplying both sides by zero and saying
LHS =RHS
What's the easy way??
In the "Virtual ground" video.
3:19 can anybody please explain why Vr1 = Vin - v(-) ?
Hey bro how are u, the ans is 2^2. Thank you. Have a nice day.
you're amazing
I must say this seems like Nicholas Cage doing the VC
just take v not out as a factor
Dope
Why cant you use the correct symbols of a circuit?
Too confusing …
I can't find the video explaining the easy way.
ADITYA sharma see the video inverting op amp with virtual ground
please try this. i hope it will help u ruclips.net/video/NY0xD0wVTkc/видео.html
F.you
u made this extremely lengthy...
this could have been done more easily
I believe its because he said that he was going to do it the hard way with all the algebra in case someone doesn't understand if he skips steps.
please check this dear ruclips.net/video/NY0xD0wVTkc/видео.html
He literally just said that he did the easy way in another video.
ASMR
WTF
11:23 should have said that from the beginning!!!! What a waste of time!!!
Thanks anyways
Luck to all
I think you completely missed the point of this video :D
