Superposition Theorem Explained (with Examples)

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

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.

Minor Correction at 11:50 ; It's 2*[〖√9+√25+√49]〗^2

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

[umasrivastava]

the circuit will look like this”

Thank you sir.

[sharminmonika]

Though you are so fast, your tutorials are really clear, educative, and informative.Thanks a lot.

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

[aryantiwari]

very nicely explained ....you did a great job by creating this of which i am able to comlete my syllabus quickly, ,,,you explanation is out of remarks....finally

[karimfaizy]

bro do not avoid that people make on you critisim. this is your excellent point.

[olaoluwaomopariola]

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

[paramjitkaur]

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

[storyofmaldives]

It'll be a good idea to put subtitles

[amaytiwatane]

Put one video of Tellegen's theorem

[rajabhay]

Super way to make understand bro.. thanks a lot

[yashwardhansingh]

worth watching videos. what software do you use ?

[mastrammeena]

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

[swapnilsingh]

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.

[techieboy]

I have a doubt in 3rd ques that how you decided direction of current source when you considered 2A as current source

[dimitrisfotiou]

thank you rly your examples make me understand the theorem

[nemalasurya]

your way of explination very clear..thank you so much sir

[animasgaming]

This video cleared my doubts thanks sir keep uploading

[techgamer]

nice work I want more problem-solving circuits hopefully u will do that like this video
