Supernode Analysis is

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.

Thank you sir....?great explanation.??many confusions got cleared regarding super node analysis...
Please suggest me a trick to know the leaving and entering currents when current directon is not given.. always a facing a bit confusion on this current directions..

arief saferman

sorry just want asking why on tbe previous video the current that connect 2 supernode can we neglect but in last one we count on it??

## Supernode Analysis Explained (with Examples)

In this video, you will

In this video, you will understand what is supernode in the electrical circuit with examples.

While solving the problems using nodal analysis method, sometimes you may find a voltage source between the two nodes. And if you try to solve such problems using nodal analysis technique, then you may find difficulty in writing KCL equations. In such cases, the concept of a supernode is quite useful.

So, in supernode, we consider the two nodes (between which the voltage source is connected) as a single node and write a single equation at this supernode.

So, in this video, we will understand the concept of supernode with examples.

Timestamped links for the different topics in the video is given below.

0:28 Nodal Analysis Method

2:56 Concept of Supernode

5:39 Solved Example on Supernode

This video will be helpful to all the students of science and engineering in understanding the concept of supernode in electrical circuits.

Dhairya Verma

this explanation is too good

MrAnperm

How did you get 30? @1:42

Higi

2:09 for node 2 it should be v2-v1

gimmedaloot754

Thank you for your clear explanation. Good job. Been out of school for a while now and am studying for my EIT. This was sooooo very helpful. Thanks again.

Umayal SAI RAM

Why -3A in super node first equatiin it entering cureent only know

Bro what to do if there's 3 such nodes what to do

Rijohn K Pius

Sir what if a resistor is connected in series with the voltage source between nodes.is that a supernode case??if not how to solve such a problem.??sir,could u pls make a video on that.

Deepthi

Simple and perfect explanation....Thanks...Keep it up

mr. unique

at 6:03 how i decide which node i take as reference ????? why i should not take node 3 as reference ???

DAWAR PRODUCTION

1st example me V2-V1/5= V2+2

Aayega na sir na ki
V1-V2/5=V2+2

Abdalla Ahmed

the voltage source terminals should be opposite no? current enters through the negative terminal and leaves through the positive terminal right? that means that V2 has higher potential than V1 as current always flows from higher potential to lower potential? so it should be V2-V1 at 4:50 ?????? please clarify

Huell Babineaux

I have a supernode ... in my anus

awesome

Gaucho Panocha

8.28 u cant math!!!!

Sri Nivas

How can we calculate power delivered by that single voltage source

nk shroud

Awesome channel

Hari Prabhakar

sir I have one doubt in example 2 of supernode analysis in that circuit upper we have 1A current supply we dont take that in solving........ for what we dont take that in our prblm.... i have another dout sir in nodal analysi example 2 when we want current i 1 we have that i1=va-v1/r1 appadi than a potu kandu pidikanum neenga v1/r appadi solve pandringa athu crt method aaaaaaa

죠스바

There are only 2 weeks left to me and this vid really helps me study suprenode problems. Thank you very much.

Suvro Sawon

Normally we took inward current to a node is positive, but why we took that as negative for a supernode??

Thy Nguyen

why is it that I1 and I3 comes out but not coming in?

Lakshya Sethi

i didnt understand supernode :(

Ghanshyam Soni

Sir are you faculty in ADIT?

shuaib kaleem

how he replaced 5 ohm with 2v

MiranChucky

10q

anik bhowmick

if a resistance is also present in the supernode. how can I do it ?

Christopher Reyes

One like, just for the accent

in equation 3 why did we say V2 - V3 not V3 - v2 ?

Bilal Mumtaz

Sir??
For supernode we offed all other circuit except supernode. ??

If a resistor os also connected with votage source in case of supper node the how can solve these types of problem pls reply.

Sachin Bhusal

what if there is resistor and voltage source between two node?
is that a supernode case?

SANJAY KUMAR

खूब सुन्दर ?

Uday Kiran

Binod

sanjay ganesamoorthy

Bro put many vedios

DP Enterprise

Very well explained, you say in minutes what my teacher takes the whole class to do

At 6:42 why 2A current at v3 not considered while writting kcl equation

Reuben Goh

Thank you very much. Awesome and clear explanation, I can understand school now

bitan pramanik

At 7:24mnt,at node 3 how the equation comes i2+2=1??

Emilio Vargas

2:56 starts

thanks bro , really likes the video. in future please do algebraic more clearly and try not to skip it . thanks bro

Giovanni Vielma

I don't ever comment but thought your video was good enough to say so
Thanks

poorna chandra _5125 Ec 07

please explain in detail of super node

hrez

Tarang Ghetia

Not Zuhri Ashraaf

Thank you for teaching me?

minazul khan

how u have decided sign of current ( minus 1 amp ) in second example equation 1 ...similarly in eq 3 sign of 2 amp

Christopher Cantieny

when solving for node 2 - it should be (v2 -v1)/5. I put this into the simulator LTspice and it checks out that way.

Vani Reddy

What if there is a resistor kept in series with the voltage source? Will it still be a supernode?

Sanoj Shrestha

Thank you great explanation

Pushkin Nagpure

When you say voltage at a node, what does that mean? Aren't voltages measured between 2 points?

Charles Azevedo

At 5:36 the top left current it is not 2A or is it? Isn't that 3A?

Bro why u take the -3 in supernode problem,i mean you take negative when current was entering why????

Abhay nayak

Thanks bud ?

at 4:19....u took ( -3) but it should be +3 as u told in ur previous video, current entering a node is considered as positive ?

Mayur Shah

excellent, nice presentation

Ťêjã Y

Video starts at 0:25

PARAMESWARA RAO

A VERY NICE VIDEO SIR

the best video out there

Dipti Shah

well Explained..

Jitraj Jana

my dear sir what is the most important criteria to select a supernode otherwise it's little bit confusing that the super node that i choose is correct or wrong. kindly reply it sir.

jeff sam

current entering the v1 junction must be 3A at 5:28

why for the equation 2 is v2-v1=3, and why not v1-v2=3 can some one explain to me, im a bit confuse

Sudeep Saha

Good. Informative.thanks.

What does the negatives potential shows in first example V2= -1v

palabandla babu

What if resistance is connected in series to the voltage source in 3rd problem

durgansh taneja

In the last example, what if there is another voltage source between v2 and v3 ?

Real Me

Jahin Mahbub

I hate your accent , but it was a good video.

Hardik Singh

was it necessary to solve for node 3 since we already know current in all three branches

anik bhowmick

than you
