The unique thing about u is that u tell us before, the points or steps where students can do mistakes. Which helps us to do more concentrate on that points...
Hii sir, at time 13:23 to calculate i(0+) can we use the concept that...current will flow the less resisitve path and 10A current source and 5A current source will flow on tht resistance free branch in opposite direction ...hence 10-5= 5A current
Sir you are awesome.....you picked up very good questions and the way you teach and explain is excellent......I never saw someone teaching so well........ besides being a good teacher you are a good person also.........I have a lot of respect for you.
before watching explanation i was having the confusion on the concept of current through a short circuit branch when parallel inductor acts a current source at t=0+ now its clear....thanks a lot.....plz explain more such interesting questions
Sir, in the second question (2017 roorkee) while calculating i(0+) we used current value in inductive branch - 5 amps. Now this current will cause a voltage of 25V across 5ohm resistor. If we follow passive sign convention then total voltage across shorted branch will be equal to 25+voltage across inductor. Ab voltage ko zero hone k liye inductor ke across voltage ko minus 25V Hona Padega. Lekin ye passive sign convention ko defy karega. Aur agar aisa nahi h to ohms law fail ho jayega... Thank you sir..... Sir aap bahut mehnat Karte hai. This motivates us...
Thank you so much sir a conceptional class once again... Sir I have one doubt regarding Q)5 means @t=0+ inductor acts as Current source but you have taken inductor directly.. I dint get this sir
Thanks sir. I have no idea & no concept of transient earlier. But by seeing your starting just 3 lecture on transient. I have solved most of previous years qns of transient.It is the result of your miracle. Thanks a lot sir. You are great sir.🙏
Sir , untill now I have never seen any sir to upload gate questions video and the most important" How to solve that gate question ?"......I'm not getting the words how I thankful of you Sir.....just wants to touch your feet sir.
At 16:34 .. sir you have used equation for current through a switch.. how is that correct? current thru switch does not show continuity hence it cant be used for a switch. the 0+ and final value for inductor is 5A and 0A resoectively, not 5A and 10A. PLease check sir
sir abhi tak mujhy apny m sirf coaching factr ki kami lagti thi bt I started to watch your vedio since Feb nd I think my coaching factr drawback will reduce thank you so much for all your help full vedio .
Your explanation is very more easy and wonderful concept than other teacher so please one video on MOSFET theory ( channel length channel bandwidth etc)
thank you sir , the problem explanation and various approaches to solve it are really helpful. especially the laplace method of cross checking was sublime....
Thankyou very much sir,video provide Krne ke liye. Mujhe bahut help hua hai apke video dekh kar padhne par. Pura concept clear ho rha hai .Sir please Network Theory ka AC circuit Analysis ke basic concept and previous year GATE questions par video bayaiye. Iss Topic par basic concept clear nahi hai mera.. please sir help kijiye..
In question 4, When finding i at infinity, the circuit becomes a current source with a short circuit. Is it possible for a circuit? As it would not satisfy kvl?
When doing RC circuits video plz tell us when it is useful, current equation for capacitor i = C dV/dt; when connected to DC source apart from transient.
Thank u sir....sir pls provide a video for output power formula application oriented math in power electronics like p=vi /p=vicosf/ (p=Vrms2/r) for various load. when which formula is applied? and also provide a video for capacitor charge storing math in network....
Sir in the last question..when switch was initially closed and we got inductor currect at t=0- equals to 0A, My doubt is that at t=0+ as u said that thru KVL we will get the voltage=10v across inductor den how can the current across inductor be 0 now at t=0+. now it will start charging so is it because that t=0+ is very close to t=0 and it will have current in steady state but not at t=0+??? pls let me know if my answer is correct. thank you for wonderful lectures. im preparing for gate thru ur vdos only at my home. it helps me a lot.
Sir what happened if two inductor connected in parallel will current devide in both ckt in steady state condition?? Or we will go only for the main one about which voltage asked
Sir please also provide some basic Communication system theory lectures from Saket sir. Its not easy to understand Communication system through questions only.
Current short ckt se flow hoega uska sawal hi nhi uthta kyuki 0+ ke analysis pe inductor current source ban jaega. Closed switch ke across 2A flow hoega.
Sir please discuss that concept that we have to add voltage source in laplace domain sometime we have to add current source . We are facing problem in that concept.
Sir hamne pahlese laplace transform through ye topic padha he so now m getting difficult to keep remember how to solve this problems.so can i go through the laplace for this topic?
sir in question from year 2017, the time constant was solved out as 0.5 sec and in question we need to find value of current at 0.5 sec of t value .it means they are asking value of current at first time constant which is always 67% of peak value (10 A in this question) so the anwer could be 6.7 amp but we got 8.16 amp here in answer . how ?? please clear my doubt why we got excess value (8.16 - 6.7=1.46 amp).
This equation is not of the form Yo(1-e^-t/T) , it is of the form k + Yo(1-e^-t/T) = 5 + 5 (1-e^-t/0.5) , so for such form the time constant for charging definition 63.2 % of steady state value does not apply. You can see earlier videos for transient for this explanantion..
Sir as in the last Question U took another example than switch was initially closed So inductor was not charged but when the switch is opened then due to no initial current in it so inductor retains its property but after t>0 it becomes RL ckt so now it can be charging or not......
Sir when there is dependent present we cannot use kvl with it like in first quetion if i use kvl in 10 A current source and with dependent source in loop it gives different answer ??? Anyone plz solve my doubt
The unique thing about u is that u tell us before, the points or steps where students can do mistakes.

Hahaa i also did witH THIS method.
Yes sir. Ap jo transient k questions le Rahe ho...unse concept bahut hi ache se.. clear hora h..!! Thanks sir

Thank you very much, Sir. I sincerely appreciate the hardwork and dedication of yours and the entire team of GATE ACADEMY.
If our college professors taught like this....hm sachhe engineer ban jaate....you are great sir
Sir how to solve network by Laplace upload some video on that topic..😃😃
u r really best teacher of network in the nation
sir at 28:35 when initial current IL 0- is zero. IL 0+ also zero. but do you mean IL( infinity) also zero??
even i have taken classes from madeasy but u r far away in explaining any concept from them.....Gate Academy rocks...plz upload more videos sir...
thank you sir , the problem explanation and various approaches to solve it are really helpful. especially the laplace method of cross checking was sublime....
absolutely perfect teaching by gate academy.. thank you so much sir
sir u always understand our basic problem where we stuck

thank you for wonderful lectures. im preparing for gate thru ur vdos only at my home. it helps me a lot.
Excellent Sir! Thank you!
1 week of long wait....!!
Dhande sir !!plz power electronic
Sir what to do when the system is with source transient then what will be our approach to solve that type of problem??
but sir as you told at t=0 plus pe inductor replace by current source, why we would not use it here?
As always super sir ji 👌😊
Nice video Plz upload video on capacitive problems
Thanx sir transient samajh a Raha ab
sir when we get the value of (iL-negative) then can we equal (iL+) by inductor property directly?? in question no. gate 2005 iit bombay
Sir what happened if two inductor connected in parallel will current devide in both ckt in steady state condition?? Or we will go only for the main one about which voltage asked
Thanks for this video lecture sir
धन्यवाद गुरु जी |
Sir in q5 at t>0 a short ckt path is present in parallel with inductor so that 1 amp current should flow from short ckt path??
For question number 5 , can we also apply inductive property ? Because we know i0- so i0+also same?
sir, may this transient can be treated as u(t)
Thank you sir. please upload RC and RLC videos as soon as possible .
Sir ne 1st question me aapne indirectly 10u(t) ko short circuit bna diya at t
Sir is solving at t=infinity there is no need to solve at t
thanks sir plz upload videos on Rlc circuit for transient analysis
Nice explanation sir ...
Sir please also provide some basic Communication system theory lectures from Saket sir. Its not easy to understand Communication system through questions only.
Current short ckt se flow hoega uska sawal hi nhi uthta kyuki 0+ ke analysis pe inductor current source ban jaega. Closed switch ke across 2A flow hoega.
Sir please discuss that concept that we have to add voltage source in laplace domain sometime we have to add current source . We are facing problem in that concept.
Sir..... Where r you???Plese upload any videos more....We r waiting....
Sir hamne pahlese laplace transform through ye topic padha he so now m getting difficult to keep remember how to solve this problems.so can i go through the laplace for this topic?
Sir 1 question of two time constant I am confused while how to solve when 2 time constant came
In question 4, is it correct to write a transient equation for a current flowing through a switch?
SIR u r the best
sir in question from year 2017, the time constant was solved out as 0.5 sec and in question we need to find value of current at 0.5 sec of t value .it means they are asking value of current at first time constant which is always 67% of peak value (10 A in this question) so the anwer could be 6.7 amp but we got 8.16 amp here in answer .
how ??
please clear my doubt why we got excess value (8.16 - 6.7=1.46 amp).
This equation is not of the form Yo(1-e^-t/T) , it is of the form k + Yo(1-e^-t/T) = 5 + 5 (1-e^-t/0.5) , so for such form the time constant for charging definition 63.2 % of steady state value does not apply. You can see earlier videos for transient for this explanantion..
Sir as in the last Question U took another example than switch was initially closed So inductor was not charged but when the switch is opened then due to no initial current in it so inductor retains its property but after t>0 it becomes RL ckt so now it can be charging or not......
Same question sir...plsss reply.
Sir please answer .........
Thanks for nice videos
Thank you very very muchhh.... Sir...
Sir plz upload some videos on important topics of Microprocessor
Sir in question no 4 i at infinity in inductor is 0 but you took 10 amp to calculate i(t)
sir pls upload a lecture on sinusoidal steady state analysis
Sir when there is dependent present we cannot use kvl with it like in first quetion if i use kvl in 10 A current source and with dependent source in loop it gives different answer ??? Anyone plz solve my doubt
Thankyou so much sir...
Nice sir opamp ke videos bhi jaldi se provides karwa do sir plz i need very much so i can clear my concept so plz sir early as possible thnks
SIR IN LAST QUESTION WHY AT t=O+ inductor doesn't replace by current source?
In que no. 5 ..sir wt d mng of statement "inductor is ideal"
rahul tak ideal coil with r=0 ohm
Sir please capacitor ka bhi upload kr dijie ..... Jaldi se
Sir please upload videos on Laplace transformation
Thank you very much Sir
Last question no.5- Third method is not properly cleared, I mean current through inductor finally becomes zero, bt ans is 1A.
Because i(0-) = i(0+) for inductors. Current at steady state is 0A, but immediately after switch closes is 1A.
Sir, please upload the video of locus diagram, thanks in advance
What will be the value of I(infinite) in last question? I think it would be 1amp
Sir Q no 4 me switch current =apply kcl at inductor current is at 0.5 sec....ans same aa rha
Why the power electronics videos stopped coming..??? When will it resume...??
why are you not posting videos of maths ...eagerly waiting for those sir ...please ...its a humble request
