Chua’s circuit

What about the output impedance?

Thank you for your effort, so how can we bring a device that gives 0-20mA analog output to 4-20mA without a converter ?

Why is the 5 ohm resistor not calculated in your final drawing?

You should calculate the steady state voltage of capacitor Vc(oo)=(Non zero value) since we have as dependent source in the path so must find the thevenin equivalent voltage acrosss capacitor to solve for steady state volatge on capacitor which you consider zero (Thats wrong) and hence further ananlysis goes wrong because this is the not the ordinary case of indenpendent voltage/current source . Correct me if my approach is wrong.

unreal video, saved my exam

At 1:25 , Why is this node referenced to the ground? Isn't there still the 10 Ohm resistor in the way?

I love your videos, thank you sir. They are helpful for fundamental circuit 1 concepts!

Excellent video. Thanks so much !

Sorry, I found this totally unhelpful. Mostly just assertions without explanations. A very poor attempt at teaching a concept.

excellent explanation thank you!

Really appreciated this video. It helped me a lot. Thank you!

Bro saved my life

Hi

I tried other videos and somehow the method wasn't working correctly. (I must have messed something up). I followed this method of naming everything with I1, I2, I3, etc and it worked out perfectly. Thanks!

Well explained. Thank you.

Hi ı want use a Pt100 at 4to20ma at 24vdc and Pt100 Will run 0 cantigrat degree to 100 cantigrat degree you can help me for circuit diagram

I love you

i tried these formulas with R=1k and cap 4.7uF and getting some huge numbers , not matching reality

You keep talking talking talking but what about just giving the 2 threshold formulas which are essential to understanding the schmitt trigger workings? No just blablablabla

at output of an opamp we cannot apply KCL

Thanks

This is one of the best explanation I've seen

Can you show that circuit doing useful work like powering a bulb or motor?

So easy when explained right... thx a lot

So hard🤔

great job!!

Thanks a lot for this video, it helped me a lot

Thanks for the informative video🙏

This is really hard to follow. I'm not college educated so that could factor.

Very good. Thank you.

Is it always given in the question if the Op Amp is ideal or Non-ideal or is there a way to tell if it is ideal?

Awesome tutorial. I can see your channel taking off in the near future.

amazing video, keep going

Sounds like a nonsense for me. If ideal opamp has infinite input resistance, you, in fact, have voltage divider which consists of 1k resisotor and infinite input impedance resistor and due to voltage divider formula voltage drop across 1k resistor should be small, not Vin. All this opamp circuits seem to be completely magic.

I like to use Millman's theorem for non inverting summing amp for those non inverting branches. It gets rough when you have more than two branches but Millman simplifies it

1:58 isn't it V2-Va in the numerator for second current? Edit: Oh, sorry my bad. i1=-i2 which changes signs for the whole numerator. Everything seems good

Much appreciated Sir😊 Easy Use it for why ??🫡

Very well explained!

Much appreciated Sir 😊 30secs for vo/vi

IMPORTANT: A novice might confuse for NON-ideal amp Ao (A_open_loop) with Af (A_feedback) = -2k/1k = -2 in the case shown above Ao =1,000 Af = 2k/1K =2 Vin = +1v , Vo = -1.944v so e(-) =0.006v; e(+) = 0v (Gnd)

Thanks

Love the video. Thank you.

Good. Thanks 👍

simply amazing

Thank you

What software you have used to draw the ciruits? I mean black background with white sketch?

There is no such thing as negative resistance.

perfectly explained.

excellent tutorial. Good luck with your channel
