Supernode Analysis

Supernode Analysis is discussed in this lecture.
When a voltage source is connected between two non-reference nodes then it is called supernode.
In Supernode Analysis we identify the supernode and apply KVL and KCL to find the node voltages.
Solved examples of supernode Analysis are discussed in this lecture video.

[@cattrader-r]

For the 3rd example; why didn’t you have the currents flowing through the 3 Ohm resistor and 6 Ohm resistor into the second super node; because initially you made the currents flow outta the first supernode ( V2 -V1)/ 6; meaning the current was flowing from v2 to v3 out of the first supernode and going into the 2nd supernode. Likewise, at supernode 1, you had the current flowing from V1 to V4 across the 3 Ohm resistor; but doing the KCL for supernode 2; you did it the other way round. Can you explain this ?

i don't understand how u got the second supernode equations

[@raviteja-sw3yk]

in ex 2; why can't use of 10 ohm resistor

[@mkwriterchannel1375]

sir great explanation good work i think in last question Vx=v1-v4/3 instead of v1-v4 can i right sir please reply me sir soon

[@KishoreKashyap]

Let me check

[@KishoreKashyap]

I have used Vx = V1 - V4

[@KishoreKashyap]

For supernode 2, KVL is V3 - 3Vx - V4 = 0

[@mkwriterchannel1375]

@@KishoreKashyap but why sir can i write this equation as v1-v4/3 but you don,t use resistor

[@KishoreKashyap]

I didn't use resistor because I applied KVL which is difference of voltages.

[@abdurrehmanafzalwarraich9210]

in third section when there was 6ohm resistance common in two supernodes you said no need to write current in that resistance...... But in last section there is 3ohm resistance common in two super while you wrote it in your 1st KCL equation???Why??

[@ephraimbsevilleii5885]

In the 3rd equation .. is node V2 not a reference node??

[@eehub6710]

Sir pls tell me , if a resistor is connected between 2 supernodes than we won't consider that resistor??? Am I correct sir pls reply 😀

[@KishoreKashyap]

If resistor is connected between two supernodes without a common node then we have to consider the current through resistor in both KCL. If resistor is connected between two supernodes with a common node then we don't need to consider current through that resistor.

[@manishapapu5458]

@@KishoreKashyap sir but y v should not consider that resistor with common node

[@shreya2864]

@@KishoreKashyap reason????

[@Shogun507]

@@KishoreKashyap What's the reason behind that?

[@KishoreKashyap]

@@Shogun507 the currents through the resistor connected between the two nodes of a supernode will cancel each other. Suppose two nodes of a supernode are V1 and V2 and resistor R is connected between V1 and V2, then in same KCL equation we have to write current leaving from V1 to V2 through R which is (V1-V2)/R and current leaving from V2 to V1 through R which is (V2-V1)/R. Now (V1-V2)/R + (V2-V1)/R is 0.

[@santoshupadhyay3103]

Sir , in last example there are 4 unknowns I am not understanding how to solve 4 simultaneous equations .. please sir reply and help me

[@KishoreKashyap]

I used Casio mobile app to solve equations with 4 unknowns. You can solve it by substitution method or elimination of variable method.

Is there any mistake in last one? in KCL1 how did he get V4/3?? im not understanding it, can anyone explain

[@uetean7270]

All my numericals are present in this video

[@mkwriterchannel1375]

sir if i get a dependent current source and circuit in same branch then what i should do tell me please sir

[@KishoreKashyap]

Then voltage relation remains same Vx = V1 - V4 and if I have to apply KCL then for current I will write the value of dependent current.

[@10.krishnapratapsinghbaghe4]

Sir I have one doubt in second question, Why we are not considering 10 ohm resistance

[@KishoreKashyap]

Because 10 ohm resistance is connecting the two nodes of a supernode, so no need to consider the current through 10 ohm resistor while writing the KCL for that supernode.

let me u after subs the eq 3 v1=20+v2 then u sub into eq 1, 2, 4 then u do the simultaneous in your calculator to get v2 v3 and v4...after that u can get v1 by sub v2 into it....i hope it clear...byeee from Malaysia
