Sir mai aapko khbai v solutions ke liye follow nahi karta..balki aapke concepts ke liye karta hu.. issliye agar waqt thoda adhik v lage toh v koi baat nahi sir..bas hamara concept clear hona chahiye taki hum exam mai jaldi bana paay.. Thanks sir😍🙏👌
i was not very sure of solving the problem at first but with that one sentence just try it for once totally changed my mind .... at first i was following differnt academy for concepts from there i got some basic idea but the way you handle every circuit is just fantabuluous.
sir, have a question. Suppose in a network, there are three sources- one current & two voltages and current in a branch is required. In case of superposition, instead of calculating for 3 sources differenty, can we take two voltage sources together & then the current source differently & calculate currents for them in two steps?
Sir, a second approach for Q5: gate 2014 Electrical Engineering. At 17:40 I want to know if this is correct way... Rs = (k^2) * Rp k = N2/N1 = 2/1 = 2 Rp = 1 ohm (given) So, Rs = (2^2) * 1 = 4 ohm And this is a step up transformer so, voltage will increase by factor of 'k' so k*Vin = 2sin(wt).
Sir last question me Maine bina two-port network k Nikal Gaya tha: N2/N1=V2/V1, isse V2=2sinwt Now we when we refer the primary Impedance of transformer with respect to secondary winding, we multiply the primary Impedance by square of transformer ratio. 1x2²= 4 ohms. Please reply if approach is right or not?
Sir, we can solve the second question much easily if we refer the quantities to the secondary side. Also, how can transformer action be valid if we are applying dc voltage in secondary to evaluate Zth?
At 22:00 transformers question explanation is little wrong as we can’t say that because secondary current is zero so primary current will be zero as there will be no load current which do not depend on load or secondary cutrrent.
Sir ye question transformer referred parameter se kar sakte hai kya Transformer Idea hai aur referred R'=4 ohm aata hai jo ek hi element hai total secondary mai
In last question during the finding of thevenin impedance, the ac voltage source becomes zero then how can the current i1 can flow in the primary side??
SIR WHY THE CURRENT WHICH PASSES THROUGH THE 2 K-OHM RESISTOR IS TREATED AS POSITIVE? FROM THE CIRCUIT IT IS EVIDENT THAT THE CURRENT THROUGH THE 2 KOHM RESISTOR IS AWAY FROM THE NODE SO THAT CURRENT WILL TREATED AS NAGATIVE..
in 1st part the circuit was open circuited so no current will flow, bt in 2nd part the circuit is closed so current will flow , assumed that the current will be I(dc)
you are not only teaching but also boost our confidence ...
great lectures

Even the below average students admires your explanation...Really hatsoff Sir...👍👍👍
Great way of explanation (Conceptually very strong)
i was not very sure of solving the problem at first but with that one sentence just try it for once totally changed my mind .... at first i was following differnt academy for concepts from there i got some basic idea but the way you handle every circuit is just fantabuluous.
In easy way .great teacher forever ❣️😍
hatsoff sir ,great lecture.
Thank you sir.... Ur teaching style is very good .... N surly it is going to help us in GATE 18
superb professor u are ..... concerning like, we are yours own students keep it up bro
you are the best teacher in the world really
how many times student appreciate does matter sir but but you always surpassing the expectation@umesh sir
Last question is very good sir. Nice explanation... Thank u sir
U are rock sir.
Tnk u sir mujhe super node nhi samaj main aah raha tha abb video dekhne ke baad aah gaya tnks sir
Wow sir...fantastic explanation...thanksss
Wow sir love u sir ye sab koi batata nhi
thank you so much sir... For providing free lecturs...
U r best..
Question 5
Thevenin Impedance can be find out by reflected input impedance of transformer.
R(Input) = n^2 R(Load)
Just change the reference
Very good sir head off u sir
india ke aap best teacher hai
Thnks for clearing the concept
Thank sir for clearing concept.
Supernode ka concept clear ho gaya.
Nice concept sir...
Thanks sir for your time and effort.
Sir your lecture Very great.
Only one request Upload krne se pahale Sound amplifie kr dena sir
Bcz sound bahot bar ekdam kam aata hai 🙏🙏🙏
thanku soo much sir .Sir u r doing great work for us .Its really superb
Thanks so much for sir for creating our concepts
i want to start from zero but through ur videos iam not be able to
Thanks sir
sir, have a question. Suppose in a network, there are three sources- one current & two voltages and current in a branch is required. In case of superposition, instead of calculating for 3 sources differenty, can we take two voltage sources together & then the current source differently & calculate currents for them in two steps?
Thank you very much sir
Sir we can also find thevenien resistance by open circuit voltage divide by short circuit current
Yes bro same ans hi aata h
Sir, a second approach for Q5: gate 2014 Electrical Engineering. At 17:40
I want to know if this is correct way...
Rs = (k^2) * Rp
k = N2/N1 = 2/1 = 2
Rp = 1 ohm (given)
So, Rs = (2^2) * 1 = 4 ohm
And this is a step up transformer so, voltage will increase by factor of 'k' so k*Vin = 2sin(wt).
thank you sir jiiii
Sir last question me Maine bina two-port network k Nikal Gaya tha:
N2/N1=V2/V1, isse V2=2sinwt
Now we when we refer the primary Impedance of transformer with respect to secondary winding, we multiply the primary Impedance by square of transformer ratio.
1x2²= 4 ohms. Please reply if approach is right or not?
thank u sir.....
Thanks sir.Sir please upload videos on 2 port network.
thank you sir
Thanku much sir
Sir, we can solve the second question much easily if we refer the quantities to the secondary side. Also, how can transformer action be valid if we are applying dc voltage in secondary to evaluate Zth?
sir...please solve one question by assuming v=1v or unity current
I tried and I solved it.
yeh!!😁😀😊
At 22:00 transformers question explanation is little wrong as we can’t say that because secondary current is zero so primary current will be zero as there will be no load current which do not depend on load or secondary cutrrent.
In the last question if we refer primary side on secondary we will be able to solve this problem in few seconds..
sir kyaa ham two resistors paraleel hai unka eaquivalent nikalke mesh analyis apply karke
thevinien resistance nahi find kar sakte kya
Getting wrong
nice
Sir, will it be wrong if I use the formula (R1/R2) = (N1/N2)^2 to find the Rth?
Yes
Sir ye question transformer referred parameter se kar sakte hai kya
Transformer Idea hai aur referred R'=4 ohm aata hai jo ek hi element hai total secondary mai
sir plz diode as a clamper circuit ka video upload kijiye ..
In last question during the finding of thevenin impedance, the ac voltage source becomes zero then how can the current i1 can flow in the primary side??
sir opamp ke jyada question provide kijiye .with schmitt trigger and other important concept plzz sir
sir..how to get previous gate solution material from gate academy?? plz provide link to buy
wowwwwwww
Sir , why u give the direction of current I2 opposite to the load terminals?
V1/v2 = 1/2 sir could you explain me why do you write i2/i1 (since v directly proportional to I) you have to get i1 /i2 explain me sir
5:37
Sir diode as clamper circuit upload kijiye
In second question can we use equivalent circuit of transformer???
Where to watch thevenin theorem??
I have noticed one thing that sir's way of writing ohm symbol is different
Ckt ko refer to secondary krke krna easy padega..
sir can you please upload problems related to 2-port networks
Sir last question can be solved by using the concept of transformer.
Sir, if we calculate Rth here by using formula Rth = V(open circuit)/I (short circuit) , then I am not getting the same result.
Check your calculations... I'm also calculated Rth by same method and get correct result
supernode mein one resistor connected hai series mein, then how will it solve ?
SIR WHY THE CURRENT WHICH PASSES THROUGH THE 2 K-OHM RESISTOR IS TREATED AS POSITIVE?
FROM THE CIRCUIT IT IS EVIDENT THAT THE CURRENT THROUGH THE 2 KOHM RESISTOR IS AWAY FROM THE NODE SO THAT CURRENT WILL TREATED AS NAGATIVE..
Sir outgoing current ko positive aur incoming current ke negative lete hain
Sir in first part of que.-4 ,you have assume I(dc) =0A but in second part you hadn't,why?
in 1st part the circuit was open circuited so no current will flow, bt in 2nd part the circuit is closed so current will flow , assumed that the current will be I(dc)
Sir neither series connected nor parallel connected ckts ke kuch examples peh video banayiye 🙏
GATE academy ka network theorem part kha hai?
Thevenin impidence nikalte hue parallel me tha to chodo jane do kyu sir wo hatke 1killo ohm ho jayega na fr kaise hogaaaa
sir 2.5 me i2 ka direction kaise decide krna hai
Why is that two port current ?
sir please computer science stream ke videos upload kijiye it would be a great help :)
Ldi/dt=0 kyon nahi hua sir , agar current 0 tha to.
people who are in your customer care are very very rude, whatever we ask they just say to visit the website.
why does it start with Q 3 & 4??? where is the 1st part?? i am confused now??
Go watch Network Theorem Part - 3 for Q1 & Q2.... But I suggest watching serial wise, as provided...
sir I2 se I1 kaise zero kiya
Not clear showing
Sayad abto iska rply bhi nahi ayega
Thanks sir
Thank u sir ...
Thank you sir
thank you sir
Thank you sir
