In this video, I explained Thevenin's Theorem, one of the circuit analysis methods. We will learn how to do circuit analysis with this theorem through examples. As you can see here, transforming a circuit into a voltage source and a resistor in series with it is known as Thevenin's Theorem. So let's try to learn how to convert a circuit into VTH thevenin voltage and RTH Thevenin equivalent resistance format.

wow you explained it so easily

I believe your 2nd circuit equation is incorrect per Kirchhoffs current law, the current source is flowing into the node so it should be positive and current thru R2 (Vx/20) is flowing out so it should be negative.

Incoming current is equal to outgoing current, Inorder to write it in the rhs he wrote it in LHS

Thanks a bunch

can you do it with a resistent that is in paralel with V1?:(

Quick question regarding the first example, why do we consider R1 and R3 to be in parallel rather than in series?

@Tyler-km8uu 4 ай бұрын

You have to short circuit the voltage source so R1 and R3 will have the same potential difference with respect to their terminals. Here short circuit means you basically remove the batteries

when you short circuit the voltage source these resistors are connected to the same nodes.

@@Tyler-km8uu You remove batteries but you also put wire there

Thankyou very much! I am confused about what the "current source" is in the 2nd example. Could you please give an example of what the current source might be? Thanks.

In the 2nd example, the current source is the 2A source.

@geoffedwards189 8 ай бұрын

@@eeapplications Yes I see that, but why is the current source different from the voltage source? Isn't the current coming from the voltage source? If not, what is producing the 2A current? Sorry for my lack of understanding.

In a current source, the current is constant and the voltage is variable. For example, when we set the current source to 1A, no matter which Resistor or load we connect, they will all draw 1A current. It does this by changing the output voltage. It ensures that the current remains constant. What is important here is my mind. If the voltage source is constant, it will draw different current when we connect different resistors.
