Sir apne concepts network theorem ke itne ache se clear kiye the pichle parts me ,ki iss question ka solution ,apka solution dekhne se pehle nikal payi .thank you so much sir ,m loving networks now. hatsssofff to u sir.
Sir, I have already solved Q2 in the transistor method earlier as i am appearing in gate for 2nd time this year. Thanks for explaining the way of thinking to others. :)
sir maine jab diagram ussi time me bolli sir ne ye qn to analog me lena chahiye tha baad me soln pe gayi to samja ki this tyoe of network can also ask in gate...n day by day mujhe bahaut hi network pasand aane laga hai bcz of u sir thank u..!#respect
Qa padhate ho ap really. maza hi aa jata hai. ekdum hamare tarike se sochna sikhate ho. yahi to chaie hume. this is the exact thing i was struggling. Respect.
On your special day...i want to say something Sir...You are not only genious you are the god father for us.... happy Birthday Sir... May god bless you ,, please keep blessing us,we need it. Thank u sir
mein jab amplifier k question solve kr rha tha aapki book se tab aisa figure aaya tha aur usme ye figure dekh k laga k ye kahi dekha dekha lag rha hai fir yaad aaya haan ye network ka b question tha,.....
haaa sir maine yasa pahele se socha tha...ar circuit vi paralell e model kiya...10kohm and RL parallel hain...current source ke sath...or 99ib dekhke hi khayal yata he bita(IB) KI
even without doing any of the above steps we can just directly find out the voltage across current source which is equal to voltage across 100 ohm resistor ...... current through 100 ohm res is 100ib therefore voltage across it will be 100*100ib=10000ib volts since current source is in parallel therefore voltage across current source is also 10000ib . therefore resistance of current source = v / i = (10*10^3 ib ) / 99 ib = 101.01 ohms now find the equivalent resistance ... thats it ... just another method that I tried
sirji, if we assume direction of current -Ib (in resister) flow opposite in Q-2 then Rth:- get(-ve50ohm) sirji, Resister is absorbing element only +ve value SO, my Q from U which sign convension use IN ANS get right result
sorry SIRJI, in my Q missing some point correct both current (resister current Ib & dependent current source) direction change & B-value slightly increse 99 to 102 then Rth get (-ve 10kohm) actully when i seen this Q & its ans then Q come in my mind independent source not present in this Q then ANSWER of Rth -ve value ( ur testseries solution this concept i see SO, i asked from U). otherwise assume any thing for -ve value but behind Q asked this concept . this concept valid particular Q or always when independent source not present in ckt or depend ON direction of dependent source given in Q.
i know its very late but if someone else is also thinking like this then please note- in this type of approach you are assuming current from terminal 1 (across which thevenin theorem is to be found ) to be zero which actually is not.... hope you got your answer
Sir opamp ka last quetion jisko ap apna fav quetion bol rahe the usi quetion ko laplace se solve karne me correct answer nhi aa raha hai pls dicuss it thanks in advance
that common collector amplifier was great. i never thought that. it brought smile on my face.

I study in Made Easy then I watch umesh Sir's video....just because his way of teaching is awesome.....hope this helps me in GATE and ESE 2019
sir maine iss que ko her baar sahi kiya ...likin kabhi aaisa nahi socha tha ki ye analog ke concept se bhi ho sakta hai......thankyou sir
Qa padhate ho ap really. maza hi aa jata hai. ekdum hamare tarike se sochna sikhate ho. yahi to chaie hume. this is the exact thing i was struggling. Respect.
Thankyou soo soo much sir.......meri sari concept clear hogyi.....tysm...UMESH SIR & GATE ACADEMY...
On your special day...i want to say something Sir...You are not only genious you are the god father for us....
happy Birthday Sir...
May god bless you ,,
please keep blessing us,we need it.
Thank u sir
sir u always provide a new concept with interesting learning .thankuu so much sir .concepts build up stronger only bcoz of u ..
That common collector part wass OP🔥
Last question of thevenin network is solved using Analog...brilliant sir!!!
Q.2 ka second solution analog vala awesome tha, maine aisa kabhi ni socha tha , Thank you so much sir
Sir mene socha tha but mene analog concept se try nahi kiya
But sir great ...Commun Controll amplifier.
thank you very much sir..... for such a wonderful explanation.... i have never thought in a way of common collector mode
Thank u sir you showed a new way of perception..... I haven't thinked in that way
Yes sir i also think in this way as i have recent watched all your live classrooms videos as well as questions video of analog
Sir..Mahool sir..
Excellent Job.. Truly loving
Sir, I actually solved in the way of analog circuit... Thanks for the motivation sir!! 😊😊
I thought of applying kcl but didn't know where to apply.
Sir mne aise sochatha, but itni easy hogi gate ka qsn to mein phirse think Karne laggya....
I have lack of word to describe your way of explanation
yes sir, i first solved using ac analysis. and got ans. within 15 sec.
mein jab amplifier k question solve kr rha tha aapki book se tab aisa figure aaya tha aur usme ye figure dekh k laga k ye kahi dekha dekha lag rha hai fir yaad aaya haan ye network ka b question tha,.....
Awesome, u change our way of thinking #respect
Awesome lecture sir
I dont think this idea.. This is a new concept. Thank u sir
haaa sir maine yasa pahele se socha tha...ar circuit vi paralell e model kiya...10kohm and RL parallel hain...current source ke sath...or 99ib dekhke hi khayal yata he bita(IB) KI
Very helpful thanks so much sir
That's why I just love GA!!
thank you so much Sir please sir complete operational amplifiers lectures series
even without doing any of the above steps we can just directly find out the voltage across current source which is equal to voltage across 100 ohm resistor ......
current through 100 ohm res is 100ib
therefore voltage across it will be 100*100ib=10000ib volts
since current source is in parallel therefore voltage across current source is also 10000ib .
therefore resistance of current source = v / i = (10*10^3 ib ) / 99 ib = 101.01 ohms
now find the equivalent resistance ... thats it ...
just another method that I tried
sirji, if we assume direction of current -Ib (in resister) flow opposite in Q-2 then Rth:- get(-ve50ohm) sirji, Resister is absorbing element only +ve value SO, my Q from U which sign convension use IN ANS get right result

Superbbbbb sir
Great Sir
Thank you sir you are brilliant
Sir plz upload some more videos on EDC- Pn junction capacitance , mos capacitor
No sir , after ur explanation i got it
Sir why can't we apply KVL in the 1st loop with Ib current across 9k& 1k and 100Ib current across 100? Ib= 0?
i know its very late but if someone else is also thinking like this then please note- in this type of approach you are assuming current from terminal 1 (across which thevenin theorem is to be found ) to be zero which actually is not.... hope you got your answer
Very very thank you sir
sir i solved second question with the common emitter approach😀
Can we use this formula, Zeq= Vth/Isc
Thank you sir.
I thought that this circuit will behave as an amplifier but didn't reach to the result
yaa sir...hybrid model jesa dekh rahatha....first thinking aayithi...but formula bhul gya tha..
Oza Aditya same here bhai
thanks
i also got the same thought CE configuration
3 phase ckt me doubt hai,pls make video if possible.....
Sir pls provide power systems for eee students.....plz plz sir
option a is correct ans
THANKS SIR
can't we apply KVL in the left branch of the ckt?
sir ,in ques. 2 can we solve by using 1amp. current source in bw terminal a,b.
Sir please provide video on mos capacitor
RAJ PAL saale nptel se dekh le....Sir ko pareshaan kyu karta hai
Yes sir... . Mene.. Analog s solve krn ka idea aya tha
Haan sirr
sir 20:18 min pe jo question hai uska answer 5k ohm aa rha hai if u converted 100ohm into 0.1ohm.
100 ohm = 0.1 k ohm
Not 0.1 ohm.
Sir please open ur branch in roorkee or in uttrakhamd state
Sir opamp ka last quetion jisko ap apna fav quetion bol rahe the usi quetion ko laplace se solve karne me correct answer nhi aa raha hai pls dicuss it thanks in advance
ans option c
sir i have thought that it is a cc amplifier.
SIR mene koi coching join nhi kiya h muj tensn ho rha hai gate k ly kyuki mne self preperation k h plz motivate
2nd question Ko Bina kcl ke bas kvl se zyada fast solve ho Sakta hai
Sir 2nd questions ma if hum 1v dc source la kar solve karta hu tu 100 ohm answer aata ha....
Please sir ....
I thought it was a transistor. But did not get the configuration.
Sir in second question Ib=v/10000. Why answer is wrong I take 99Ib=v/0=infinite please sir
Alok Electrical Classes why you take internal resistance zero... As it is not given ..so don't try to assume it ideal source
Mai aisa tho nai socha Lekin absey kabhi nai bulunga
Sir phle har subject ka topic wise theory or concept upload kar do..fir uske baad gate se related questions practice btana
its written part 3....shouldn't it be part 1?
me nai socha tha kuki transistor type qn nai bnta
3 phase power calculation par ek video
Nhi,but ye jaroor socha tha ki 1k &9k alag alag kyo diya h.
dhasu vdl rule for ac
Bina concept ka direct question thora samajhna muskil hai..
Han meine resistance reflection rule laga Kar kiya tha
Sir apko MIT me hona chahiye .. Head of department
😁
Thanks sir 😊
Very very thank you sir
