Thevenin's Theorem Explained (With examples of Independent and Dependent Sources)

Показать описание
In this video, we will learn about the Thevenin's Theorem in the electrical circuits.

Thevenin's Theorem is a very useful technique in solving the circuit problems when your entire focus is on a particular element in the network and you are not bothered much about the remaining network or circuit.

So, using this Thevenin's Theorem we can replace the entire circuit by the Thevenin's equivalent voltage source in series with Thevenin's equivalent resistance across it's terminal.

So, in this video, we will see that how to find this Thevenin's equivalent voltage and Thevenin's equivalent resistance.

Now, there are three different possible cases of the circuit for which we can find the Thevenin's equivalent circuit.

1) Circuit contains only independent sources.
2) Circuit contains independent and dependent sources.
3) Circuit contains only dependent sources.

So, in this video, we will see that, how to find Thevenin's equivalent circuit for all these cases with an example for each case.

At the end of the video, we will see Norton's Theorem which is dual of Thevenin's theorem and will see that how to convert any Thevenin's equivalent circuit into Norton's equivalent circuit using the source transformation.

The time-stamped link for the different topics is given below:

Minor correction:
5:30 In Case 1, the value of Vth will be 15 V instead of 5V.

I just came here to see what to do with the dependent sources. But I got to learn why this theorem is needed. Thanks for that.

anybody who is confused about voltage Vab in case 1 see below:
just apply KVL at node A like this:
0=(Va-10)/10 + (Va-20)/10
SO 2Va = 30
Va = 15v
Note: B is taken as ground so Vab is now only Va as Vab= Va-Vb

review:
Only independent sources: remove selected resistance, calculated voltage via mesh analysis and resistance via removing sources
Independent and dependent: Apply KCL on dependent sources and short A and B to find volt and resistance
only dependent: apply 1v/1A source from B to A to find the resistance, as it is equal to Va (Volt = 0)

One doubt...why to make independent sources zero while calculating thevenin's resistance?
What is the significance of this point??
Also what does thevenin's voltage actually mean

In case 1..there is a mistake...Vth is 15V not 5V

I’m so confused about the 2nd case when he shorted the resistance and the dependent source. How?

Why in the second case, didn't short ckt the voltage source

5:22 The minus in the last equation should be replaced by plus
Thank you for the video, it's really of value

Sir I didnt understand how did u get Vab=10-(10i)

When u solve the problem if u hints the eqn very helpful 2 us....btw ur vedios is awesm and it is very helpful me in my study...tq

Sir suppose if we take 20v in order to find out vth then value of vth will be change

hi am a CE student....my lecturer wasn't that clear especially on obtaining the thevenin resistance....but lol...you made it simple sir..thumbs up!
