Ur teaching skills r amazing sir.But my request is plz try to explain whole problem on a single screen. Its making us to rewind and see the previous steps for further substitutions and understanding purpose sir.

[@priyapandey3959]

Prfect for Z parameter example 🙂

[@soul2197]

Have you made a video on first order circuits for initial conditions of RL and RC

[@ALLABOUTELECTRONICS]

Yes, please check this video: kzbin.info/www/bejne/garPe2WsZsSWY9E

[@mnada72]

Your video is very impressive, nicely explained. but I would suggest you to make one example of transistor circuit to show the role played by input impedance and output impedance in the real world

[@electricalisfuture5008]

👍

[@gpmahendra7129]

Nice explanation. Would you please upload the remaining Two Port Parameters related video as early as possible?

[@ALLABOUTELECTRONICS]

Yes, will upload very soon.

[@dipikathakur8216]

@@ALLABOUTELECTRONICS have you uploaded the other parameter.?or not

[@usamazahid1]

keep it up the nice work....short and brief video

[@newhope5729]

Hey please tell me what is Z11, Z22, Z21 and Z12???

Thank You So Much!

How's the direction of current -I in example 2?is it because of directions chosen in first equation? Also,is it a fact we can learn by heart that lattice network is symmetric and reciprocal? How did you reach at that conclusion?

[@ALLABOUTELECTRONICS]

Yes, the direction of the current is as per the earlier equation. Because during the calculation, Port 2 is considered as open. So, no current will flow in that direction. Yes, the given lattice network is symmetrical and reciprocal. And in fact, that is also evident, if you just look at the network. But when in doubt, you can also find the remaining two parameters to check the conditions. I hope it will clear your doubt.

[@RAHUL-xy1ds]

@@ALLABOUTELECTRONICS thank you bro

[@newbie8051]

Great explanation, thank you sir !!!

[@gaganpandey7765]

In example 2 how you know this network is symmetrical and reciprocal

[@shashidhar5204]

It would be very much helpful if u share whatever u written as on ppt to us

[@RAHUL-xy1ds]

How's the direction of current -I in example 2?

[@vigneshbhaktha7]

same doubt

[@venkyvenkatesh7462]

Same doubt.. it's absolutely wrong in ex:-2 . There is Zb-Za/2

[@dungaajay6085]

cant we use nodal analysis in the first problem but i am getting v2 different from what u got?

[@santhoshiatkuri6884]

Thanks alot.... For giving a excellent explanation.... 👌👌😊

[@ohenebagyimahgyimah7057]

Please what can you use this circuit for??

[@ALLABOUTELECTRONICS]

As I mentioned in the introductory video of the two port network, for the analysis of many practical network, the two port parameters are very useful. For example, transmission line, small signal model of BJT etc. I hope it will give clear your doubt.

[@kaursingh637]

thank u sir for excellent lecture =please suggest a book

[@ALLABOUTELECTRONICS]

You can refer Network analysis by van Valkenburg and fundamental of electrical circuit by Matthew Sadiku.

[@mayurshah9131]

Excellent 👍👌

[@dhirajkumarsahu999]

thank you for the video sir...please make a video on phase-locked loop. No other has uploaded a proper video on it. Its a request sir.

[@ALLABOUTELECTRONICS]

Yes, I will definitely upload it. But as I have just started the series on Two- Port Network, so will upload it once it gets over.

[@dhirajkumarsahu999]

@@ALLABOUTELECTRONICS will be waiting for it sir..

[@12jodyt29]

Sir please provide any method to solve lattice circuits of h parameters. 🙏

[@ALLABOUTELECTRONICS]

Will cover such example on the second channel

[@12jodyt29]

Please remind us.

[@Mothers_spoon]

Sir...how did I2 become positive in the mesh 1 (example-3)

[@ALLABOUTELECTRONICS]

Both I1 and I2 are flowing in the same direction through 1 ohm resistor. That's why voltage drop across 1 ohm resistor is (1ohm)* (I1 + I2). I hope it will clear your doubt. If you still have any doubt then let me know here.

[@Mothers_spoon]

@@ALLABOUTELECTRONICS oh...now I understand sir..... thank you soo much sir 😊...

[@vimushalan]

9:14 sir in that time why you put negative sign ..."ZaI-ZbI"...?

[@ALLABOUTELECTRONICS]

Because in the Zb, the direction of current I is opposite to the direction in which we have applied KVL.

[@venkatalokesh1117]

Sir. In the last example.. We can apply kvl aslo.. Isn't it true sir?

[@ALLABOUTELECTRONICS]

Yes, there are many ways to solve one example. So, you can choose whatever method you are comfortable with.

[@its_radhakant]

At the last example, i got stuck!! When to apply KVL and when to KCL??

[@ALLABOUTELECTRONICS]

It depends on the circuit. You can also find the parameters using KVL. But here, since there is a dependent current source in between, so you will encounter the supermesh. That's why here KCL is used.

[@its_radhakant]

@@ALLABOUTELECTRONICS Now clear. Thank you

[@narendrakumarguruvu9041]

thanks for the help bro

[@raghut720]

Thank You!!!

[@pavanboda-f7s]

which book from this problem can u send me book pdf

[@schurup2994]

thank you sir

[@ralph7193]

Why in example 2 I=I/2 + I/2

[@ALLABOUTELECTRONICS]

Current I1 = I + I = 2*I. Therefore, I = I1/ 2.

No homework problem this time ah

[@fardeenbaig0013]

Sir your last example problem was wrong.

[@ALLABOUTELECTRONICS]

I have already mentioned the correction in the video.

[@ALLABOUTELECTRONICS]

Yes, will take care of it in the future videos.
