I have solved my question like that successfully with mesh analysis which the question wanted from me.

But I am just curious that how can I calculate this circuit using nodal analysis?

Here is my calculation:

and here is the question of the circuit:

I don't want the whole solution. I just want to learn which nodes should be labeled to start to solve for nodal analysis... ^^

hi cik,
This PDF explains the Nodal analysis method.

Clip;
In electric circuits analysis, nodal analysis, node-voltage analysis, or the branch current method is a method of determining the voltage (potential difference) between "nodes" (points where elements or branches connect) in an electrical circuit in terms of the branch currents.

Normally I also watched this video from the beginning to the end. But my problem is the question which I'm stuck with (about only doing node analysis. I just know to mesh analysis well) complicated circuits.

In the video, the teacher's way is useful only for basic circuits.

I cannot do the same nodal analysis technique in complex circuits.

I can solve the complex ones with the help of mesh.

So can you help me that is there anywhere to learn nodal analysis like a greek god.

Nodal analysis is conceptually much simpler than mesh analysis if you just color-code the nodes & super-nodes. Here there are two super-nodes and one regular node. So there will be 3 node equations with 3 node voltages.

hi c.
As always, post your final calculations, it will help other students.
