Superposition Theorem Explained (with Examples)
HTML-код
- Опубликовано: 17 окт 2024
- In this video, Superposition Theorem is explained with examples.
So, in this video, first, Superposition Theorem is explained using one example of an electrical circuit and then three examples based on this Superposition Theorem has been solved.
Superposition Theorem Statement:
Any linear bilateral network containing more than one independent sources, the response in any of the branches ( Voltage or Current) is equal to the algebraic sum of the responses caused by each individual sources acting alone, where rest of the sources are replaced by their internal impedance.
So, ideal voltage source will be replaced by a short circuit and ideal current source will be replaced by an open circuit.
This Superposition Theorem is quite useful when circuit contains more than one independent AC sources with different frequencies.
To apply this Superposition Theorem, the network or circuit has to be linear and bilateral.
To, know about linear and bilateral network check my other video on Classification of Electrical Networks
• Classification of Elec...
This Superposition Theorem cannot be applied for the power calculations, which is the limitation of this Superposition Theorem.
If the circuit contains any dependent source, then during the Superposition Theorem analysis, all the dependent sources are kept on. Or in another way, we can say that dependent sources are not turned off during the analysis.
The timestamps for the different topics in the video is given below.
2:23 Superposition Theorem Statement
4:21 Example 1 (With Current Source)
8:34 Example 2 (Power Calculation)
13:31 Example 3 (With Dependent source)
This video will be helpful to all student of science and engineering in understanding the Superposition Theorem in the electrical circuits.

ALL ABOUT ELECTRONICS why is v1=-i1 in ex 3
Sir..i think you shouldn't give every resistor 1π or same.if you not do this-it will help us to understand correctly which one, you are using.
@@utena8518 Lol 8 month later 😅😅😂 still thanks for telling because I was wondering the same but I figured it out and then came to comment section 😅
Even I was about to comment the same thing sir....I like the way you explain things but pls consider this request of mine....pls give some other value other than 1 for resistors to understand the same much better.......and one more thing if am not wrong there is a mistake in your calculation sir, you can't separate things within square root with squares like that while calculating Pmax......reply me if am wrong....
why did you remove R from the square root , i think this is mathematically incorrect
You make this video perfect.
I realize that it is very hard to draw figures of resistance, battery,etc.
And show slide line by line.
Good work bro
“........And the circuit will look like this”
Thank you sir.
Though you are so fast , your tutorials are really clear, educative,and informative.Thanks a lot.
bro do not avoid that people make on you critisim. this is your excellent point.
Sir had we considered that ammeter is non ideal in first case. Otherwise those two resistors will be short circuited. Also in removing voltmeter the wire was connected. But while removing 1A source u didnt removed wire which will create short circuit
Can anyone explain In 5:20, why the two 1ohm resistor can be consider as parallel but on the other hand in 5:49 the 1ohm R why is that in series with the 0.5ohm resistor
very nicely explained ....you did a great job by creating this video.....bcz of which i am able to comlete my syllabus quickly ,,,,you explanation is out of remarks....finally '''''GREAT JOB''''''
Great video, but I wish you would make your pointer brighter. I had to rewind like 4 times wondering which one ohm resistor you were talking about before I saw that there was actually a very small pointer moving to show what you were saying. So maybe make it bigger and a color like orange, so it's very easy to follow what you're explaining
in ex3 for 1ohm resistance voltage diff. is v1 so it given or we have considered it as v1 due ti dependent source 4v1 and why v1 = -i1 it should be i1 only.
I have a doubt in 3rd ques that how you decided direction of current source when you considered 2A as current source
2A current is entering the node. while the other two currents are leaving the node.
That's why there is a negative sing before 2A current source in the equation.
I hope it will clear your doubt.
@@ALLABOUTELECTRONICS thankyou 😄
I couldn't understand how did u wrote the equation by applying KCL at v1" in the last problem in 2nd case
worth watching videos. what software do you use ?
this is nothing but a good video
Sir, in the last example, the potential across the 1ohm resistance is v1, this is given in the question?
Sir,why you can replace with one ohm resistor in the case of considering current source alone
All other independent sources would be replaced by internal impedance
Quire useful - AC Sources with different frequencies
Power can't be calculated by superposition - with exam 8:45
Min power max power
By - Minimum and maximum current through load
13:48 - dependent source example
It'll be a good idea to put subtitles
at 5:30 how is the short circuit same as 2 sets of 2 parallel 1ohms? A set on the left is correct but how did the set on the bottom be there? I thought those two 1ohms would disappear since the circuit is shorted.
3:23 I just heard something... Actually a sound effect I was looking for.
This video cleared my doubts thanks sir keep uploading
at p=i2R you took common multiple of them out ok but you should have square 2 also because the square is for all the component which is radical of (square root of 25+49+9)
the 2
my second question is how V1=-I1
can you answer it plz
this question is nothing but a request
This is " Nothing But A " Comment
Kon re tu ?(
Kopargaon kr
sir ...at the last example ..v1"-2 +v2/5=0 is written...but by sign convention V1 should be negetive ....I could not understand this point
At supernode, the KCL is applied. See, 2A current is going into the node. While other two currents (V1''/1ohm) and V2/5 ohm are going away from the node. So, if you consider the incoming current as negative and outgoing currents as positive then you will get the above equation. If you consider the sign convention other way around (Outgoing current as negative and incoming current as positive ) then also you will get the same equation.
I hope it will clear your doubt.
Super way to make understand bro.. thanks a lot
Hey we have same name
Concept well understood, can i make transcription of this video?
In English it is already available. If you want to make transcription in any other language, you are most welcome. And that will be a great help.
In 1st problem, why you took I2 is zero, plz explain it sir
Put one video of Tellegen's theorem
nice work I want more problem-solving circuits hopefully u will do that like this video
Sir last question main supernode nahi lagega, please check this again.. Total current across 5 ohm will be 4/3
If you simply apply the loop equation in the outer loop then it won't require. ( I mean no need to apply the concept of supernode) but when it is solved using the nodal analysis method then there will be a supernode.
Concept is cleared ,thank u☺️
Bro.. Awesome awesome awesome..... Congrats.. It's very useful... Keeping doing😘😘😘🤗🤗🤗🤗🤗
Why is I1 negative? at V' = I1? is it because of the polarity of the resistor?
your way of explination very clear..thank you so much sir
When considering only 10V voltage source, how did the voltage across the 1Ω resistor became (-V'1)?
Because the direction of current is assumed in a clockwise direction. i.e I1 is flowing in a clockwise direction.
So, if you apply KVL, then V1' = (-I1)*(1 ohm)
thank you rly your examples make me understand the theorem
hey, this video was uploaded on my 18th birthday!
Super explanation, request from me is explain about remaining theorems like Norton's and reciprocity ,
Norton's Theorem I have already covered at the end in the Thevenin's Theorem video.
You may check that video.
Excellent 👍
At 6:21 The current that is going through the .5 ohm resistance is .25 A so the current going through 1.5 ohm resistance is going to be .75 A which is not reasonable because the larger the resistance the lower the current which is not consistent in this example because the larger resistance is 1.5 ohm and it has the lower current which is reasonable and logical.
yesss.....bro its 1.75
in the last example, how is V1' a voltage drop? the source is clearly flowing from low potential to high potential which is clearly a voltage lift. if your 1I1 is negative then your dependent voltage of 4V should be negative as well, but obviously it isn't since its experiencing a voltage lift lol.
Appreciate the effort.Thanks a lot .
someone plz explain why in the 2nd ex in Pmin we took total current as (I3-I2-I1) ???
P min = I min^2 x R. So, to find minimum power, current should be minimum. (I3 - I2 - I1) is the minimum possible value of current. And hence, it will give minimum power.
@@ALLABOUTELECTRONICS thankyou but .. y is i3-i2-i1 the min. Current??
At 11:27, I1, I2 and I3 are calculated from the given power. So, for a given R, the (I3 - I2 - I1) will make the current minimum. Isn't it ??
@@ALLABOUTELECTRONICS thankyou sooooo much 🥺🥺 this was the 1st time .. my doubt cleared via utube 🙏🙏🙏
at 15:08 how is V1 = -i1? as according to the current direction of i1, it would be a voltage rise?
with the direction of the current (Clockwise), there should be a drop in voltage across the 1-ohm resistor. but it is rising. That means assumed voltage drop V1' has reverse polarity and that's why with the given polarity there will be a negative sign.
I hope it will clear your doubt.

What's the meaning of this "Short Circuit" that replaced V2
It means shorts (the) circuit
Best explanation ever seen
Can we use mesh or node analysis while solving ckt in super position theorem
After applying superposition (Considering only one source at a time), the equivalent circuit can be solved using the node or mesh analysis.
@@ALLABOUTELECTRONICS thankyou
why arent dependent sources switched off ?
Super explanation
Sir please let me know how to make such type of video. I really appreciate your videos
Nothing but a ka taaau ,,, mstt samjhaya
Sir last wala sum source transformation se kar sakte hai...????
At 16:50 ??
No sir...
At 13:32
Yes, you can. But here since I want to show the usefulness of super position theorem, it wasn't converted. But yes, you can do that.
Sir but I am not able to do so...
Can u plz help me out...
How can I use source transformation as there is dependent variable...
I perfectly understand the concept.Thank u sir
Video helped me 👍👍
in third example, why is V1'=-I1 and not +I1
Can you add AC circuits transient analysis?
What is the defference between superposition and thevinin theorem ?
The superposition is used for linear circuits. And to find the current or voltage across the particular element, only one source is considered at a time. The overall response (current or voltage across the element) is the summation of the individual response.
The Thevenin's Theorem is used to find the equivalent circuit across the to terminals. Using it, any linear circuit can be replaced by the Thevenin's equivalent voltage source in series with Thevenin's equivalent resistance across the two terminals of the circuit.
For more info, please check my video on Thevenin's Theorem.
When you applied the current divider rule(example 1 at 6:02) you say "into 1 ohm", shouldnt it be into 1A?
Excellent explanation
In last example why is it - 5I1 and not +ve as there is a rise in that 5ohm resistor.
Because if you move in the clockwise direction, then there is a drop across the 5-ohm resistor (moving from positive voltage to negative voltage). That's why it was considered negative.
Plz keep a video of reciprocity theorem
super explanation sir thanku so much it is very useful to me
Super easy sir
Thanks so much
How to know which sources is dependent??
Diamond shaped sources are dependent while the circular ones are independent
Excellent explanation BROOOO......
U didn't explained the formula to find p max and p min..
as far as i know after replacing 1 volt with short circuit current won't pass through right and below 1 ohm resistor as current likes to pass through the path with less resistance the current will simply pass through the short circuit.
What you are saying would be true if there is a short circuit in parallel to the current source. (Across the current source)
Excellent very nice theory
excellent explanation... I'm impressed...
Hii
all good..
please be more careful using nothing but nothing but all the time..
How is it +V1' ? Why is it - to + at 1 ohm resistor?
Ya, I have also the same doubt plz explain.
Thanks for information 👍
i suggest you to decrease the use of word 'nothing but a' ,,you are misusing it to irritate us ,,lol
Lol
@@engineer1136 😂
At 12:04 made a mistake see once i.e you have to keep power2(square) for Pmax,then only we get Pmax=450 otherwise we get Pmax=30 watts....my humble request to cross check once
Yes, that's true. And I have already mentioned that in the pinned comment two years back :)
But anyway, I am glad that you have pointed that out.
Sir, u r explains super, but u scrolling bottom explained literally they disturbing main contains (circuits) , so, please observe in u contains vedios.
I think you are talking about the subtitles. You can turn off the subtitles (CC) manually in the video settings.
2:3 super thankyou sir
awsum explanation!!!👍
Hello
why at 7:50 is the current through the 1ohm resistor 0
In the Wheatstone bridge circuit, since the resistance of all the arms are same, the point A and B will be at the same potential. And that’s why no current will through 1ohm resistor at the centre.
Thank you so much 😊
Video is gud but plzz upload more question solving videos which are covering all types of questions
.file or .5 ?
And when calculate resistors .5 and another .5 where is paraler .5 resistors. I couldn't understand ur accent actually
a very good lecture
At 17:05 V2 - V" = 4V" hi kyu hua
V"- V2 = 4V" kyu nhi hua.....?
It is simple KVL. Just apply KVL between V2 and v1''. In case, if you find it difficult, replace V2 and V1'' with voltage source ( with plus - minus sign). It will help you in visualising them.
How did you find the minimum power??
Pmin = Imin ^2 *R.
Or in other words when the algebraic sum of I1, I2, and I3 is minimum. (i.e I3-I2-I1)
It's got nothing to do with your teaching. You teach very well. But by any chance are you South Indian?
Sir ur videos r super but don't write on the screen sir we r unable to see the video
Thank you!
Thank you so much bro 🔥🔥
Very good
explain the example in detail like explain each step dont just skip it
