Superposition Theorem Explained (with Examples)

Күн бұрын

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.

When considering only 10V voltage source, how did the voltage across the 1Ω resistor became (-V'1)?

@ALLABOUTELECTRONICS 5 жыл бұрын

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)

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

@ALLABOUTELECTRONICS 6 жыл бұрын

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.

@ALLABOUTELECTRONICS 4 жыл бұрын

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.

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.

What is the defference between superposition and thevinin theorem ?

@ALLABOUTELECTRONICS 4 жыл бұрын

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.

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

@ALLABOUTELECTRONICS 3 жыл бұрын

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.

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.

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.

It is because of the Ohm' law. V= IR. Here, R= 1 ohm. And the direction of the voltage V1' is assumed other way around . (Opposite to the direction of current I1. That's why V1' = -I1 And same is true at 17:23 It is actually I2= V1''/1ohm. Instead of 1 ohm if there is R ohm resistance then the expression would be equal to I2= V1'' /R I think because of 1-ohm resistor you got confused. Isn't it? Anyway, I hope now it will be clear to you. And still if you have any confusion then do let me know here.
