[@abhimanyu7858]

What about current through 10ohm during kcl

[@viewocity9840]

During KCL , If we neglect the voltage source present between two non reference nodes then the equation is V1-V2/10

[@omerfaruk1351]

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.

[@Sattiboyy]

It will get canceled when u add eqn 1 and 2 to eliminate i.... correct me if I m wrong

[@emmanuelpewah1759]

the 10 ohm resistor does not make any difference because it is connected across the supernode

[@Pablo-ho2rg]

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

[@marvii13]

May God bless you 😭💙💙💙💙💙💙

[@Ceyhus]

on 9:15 why V1 +2 = V2 but not V1-2=V2 ?

[@changerequired7851]

Because power is delivered there so you have to take positive 2

[@yourbestie4138]

only one view away from 100k for this video..hope my view completes it😂😂......Superb channel😍👍

[@BankoleAyodeleMEG]

I have a question. Since the 10ohms resistor is part of the supernode, why is it not considered during the KVL analysis?

[@klennmarvindayo4832]

Same

[@shreyasmahendra6809]

@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

[@pujithramvemana]

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...

[@madladdan]

Subscribed because of this video.

[@chanakyasinha8046]

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.

How to do if the 10 ohm resistor is in series with supernode(voltage source between 2 no reference nodes)

[@mirthun1012]

It becomes normal nodal analysis!!

[@aashitAgrawal]

what is the use of 10ohm resistance, if we replace it by 10,000 ohm resistance, will the answer be the same?

[@sugarpop2362]

Current only goes through the voltage source as it finds the path with least resistance

[@smeetkathiria9870]

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.

[@chanakyasinha8046]

You are doing good work.

(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)

[@Awesomekid2283]

@@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
