Thanks a lot for starting a series on Network Theory! Please finish this series first and then move to others as this is the most fundamental subject. I'm a big fan of your playlists for Electronics Engineering. :)
sir,,plz upload in daily basis....sincere request to you..i am big fan of ur concepts.....covering all concepts of any topic in very easy way..u r awsm sir..thanx in advance,...
I tried solving the practice problem of this sect from the same book... And whatever current you mention in the supernodes, all boils down to final equation as similar to single node... The redundant current, the 10 ohm resistance are all just to circulate their own current in their supernode... So whatever current enters 10 ohm, gets circulated back following the 2 v source, as like it had seperate path for that... But also it increases the nodal voltage and boosts the current. Aah it hurts thinking too much.
@alpino candy is the 10ohm resistor redundant here because current will flow through the 2v branch which has 0 resistance and no current flows through the 10ohm resistor because it has some resistance and hence is not a viable path for the current to flow? Or is there some other reason
i think, if we add V1-V2/10, then we have to add V2-V1/10 because the currents -left side and right side of the supernode- have to write properly. and sum of those 2 terms are 0. simply, we can say he wrote the shortly.
Why should we bother about 10ohm resistor. We only need to calculate current i ( in voltage source wire) . As we need another equation to find the unknown variable
At 1:20 = sir, if element is present, then the nodes 3 and 4 is considered as V3, V4 ? also, at 8 : 40 = what about 10 ohm resistor? Should we ignore it? why? anyone pls explain...
@@sourabhpatravale8348 Because when node V1 and node V2 are combined, the current through the 10Ω resistor from either node will cancel with the current through the 10Ω resistor from the other node, so you can neglect it
@@littlekumar8091 i know whats bothering you... Let me explain why... The 2 v part does circulate current if you measure... But that circulates only in that loop of 10 ohm and 2 v source... Think of it like a pipe where you have a black water and a white water... The black water flows seperately aside in that pipe without mixing, throu 10 ohm... Also the white water does gain energy, as voltage (pressure is boosted) so does the current... Now super impose it.... Thats why 2 v part plays important role in the analysis as it boosts the currents...its energy source. I hope you can visualise it.
as we are removing the voltage source and and short circuit it to form supernode. the resistor which is in parallel to a short circuit, can be neglected.
ok consider the supernode without the 10 ohm resistor. i.e. only v1,v2 and that 2V source. then try writing the equations. ull get two terms such as.. ..+ (V2-V1)/10 + (V1-V2)/10 ... which cancel out. thats why he said i and -i . regards..

Very direct. Nice
(V1/2)+(v1-v2)/10+(v2-v1)/10+(v2/4)+7=0....(1)
Simply 5v1+2.5v2=-50...(1) v1-v2=-2...(2) *5 ,5v1-5v2=-10....(2) ,(1)-(2)
7.5v2=-50+10
v2=-5.3v, v1=-7.3v(3minutes)
You can solve without considering the 10 ohm resistor as the part of supernode!

How to do if the 10 ohm resistor is in series with supernode(voltage source between 2 no reference nodes)
I tried solving the practice problem of this sect from the same book... And whatever current you mention in the supernodes, all boils down to final equation as similar to single node... The redundant current, the 10 ohm resistance are all just to circulate their own current in their supernode... So whatever current enters 10 ohm, gets circulated back following the 2 v source, as like it had seperate path for that... But also it increases the nodal voltage and boosts the current. Aah it hurts thinking too much.
Thanks a lot for these lectures..
I have a question. Since the 10ohms resistor is part of the supernode, why is it not considered during the KVL analysis?
Same
@alpino candy is the 10ohm resistor redundant here because current will flow through the 2v branch which has 0 resistance and no current flows through the 10ohm resistor because it has some resistance and hence is not a viable path for the current to flow? Or is there some other reason
Thank you sir
Thank you
Sir why are we including the 10 ohm resistor in supernode portion?
thanks bro fabulous work
keep it up
May God bless you 😭💙💙💙💙💙💙
what is the use of 10ohm resistance,
if we replace it by 10,000 ohm resistance, will the answer be the same?
Current only goes through the voltage source as it finds the path with least resistance
You are my hero sir,
You are doing good work.
Thanks
sir, we really appreciate your kindness toward us. you made an awesome video and it's free.
I really appreciate it, sir. thanks a lot, sir.
if its not mentioned in Question to find v1. can we take v1 as refrenced node to avoid supernode?
Awesome sir
thank you
Can You please upload the solution for the other diagram shown in the video where more than two nodes from one supernode. It would be really helpful.
thank you very much ❤❤
Subscribed because of this video.
What about current through 10ohm during kcl
During KCL , If we neglect the voltage source present between two non reference nodes then the equation is V1-V2/10
i think, if we add V1-V2/10, then we have to add V2-V1/10 because the currents -left side and right side of the supernode- have to write properly. and sum of those 2 terms are 0. simply, we can say he wrote the shortly.
It will get canceled when u add eqn 1 and 2 to eliminate i.... correct me if I m wrong
the 10 ohm resistor does not make any difference because it is connected across the supernode
Why should we bother about 10ohm resistor. We only need to calculate current i ( in voltage source wire) . As we need another equation to find the unknown variable
only one view away from 100k for this video..hope my view completes it😂😂......Superb channel😍👍
i got a question, afterthe supernode is formed, what is the value of the current flowing within the 2V Voltage source?
Great explanation.
Nice video sir ji
on 9:15 why V1 +2 = V2 but not V1-2=V2 ?
Because power is delivered there so you have to take positive 2
At 1:20 = sir, if element is present, then the nodes 3 and 4 is considered as V3, V4 ?
also, at 8 : 40 = what about 10 ohm resistor? Should we ignore it? why?
anyone pls explain...
thank you. i love you
very nice boss
Good
Thanku so much sir
thank you this really saved me

Superb explanation bro...❤️
What will be the current through 10 ohm resistor?
i am doing it using source transformation and i am not getting same answer , please help
Super bro super super 💪💪
Im confused, Why cant you just make the reference node one of the nodes connected to the voltage source to avoid having to use a supernode?
you need to put ground as a node,
Sir please tell in this question 10ohm not use for equation?
sir what about 10 ohm resistance in super node
+1
10 ohm resistor is part of supernode because it is in parallel with supernode
Sir, what will happen if the current source is connected between two nodes???
Then supermesh concept you can use
Sir how can i get pdf of all these lectures (Network theoy)?
very nice explanation :) god bless you sir !
Do we need to ground the circuit before analysis; i.e. assume zero voltage at the bottom node ?
yes u need to have a reference node which is the one that will be grounded
Wow video
What happens to 10 ohm?
10 ohm is useless across the supernode
@@lilchamp1342 but why?
@@sourabhpatravale8348 Because when node V1 and node V2 are combined, the current through the 10Ω resistor from either node will cancel with the current through the 10Ω resistor from the other node, so you can neglect it
@@Awesomekid2283 but the voltage across the 10 ohm resisisor is 2 volt if we place ammeter then it shows reading

Ans may be wrong...my ans is v1=-6v &v2=-8v
No its not.
🔥🔥🔥🔥
sir requesting to upload networks next video and also z transform
why do you get negative voltages? what does that imply?
It means that the polarity is opposite to the assumed polarity. In other words if Vab is negative, then it means Vb > Va
sir humble request you to upload more vedios as soon as possible . plz atleast two lecture upload daily.
Sir how did u obtain equestion 1
Sir why we dont consider 10 ohm resistor,.
same doubt...
what will eventually happen to 10 ohm
What reference is this sir?
Sir how to solve that problem if the voltage value 2V is not given???
Find it by using nodal analysis
Why don't you make V2-V1=2 rather than V1-V2=-2? Is it the same answer?
Check polarity of 2v so it should be v1-v2 =2
Why can't we write the eqns for node 1 : -2 + V1/2 + i +(V1-V2)/10=0 and node 2 : 7 + V2/2 - i + (V2 - V1)/10 = 0 ?
as we are removing the voltage source and and short circuit it to form supernode. the resistor which is in parallel to a short circuit, can be neglected.
Sir provide network analysis notes in pdf
Why my answers are v1 = 6v and v2 = 8v
What will happen if there is a series resistance in the circuit with the supernode
in which part of the circuit? give an example
Then it will form another node.

What about the 10ohm????
same doubt...
sir id it v1-v2=2? or v2-v1=2?
Check the polarity of voltage soure .the current will flow from 1 to 2 ,i.e v1-v
V2 _v1
