Homework Statement

From this circuit diagram assume Vs and all resistors are known.
How many independent equations can be written using KCL?

Relevant Equations

KCL

I think there are 4 essential node. So we can write 3 KCL independent equations.

why do you have one node with 2 labels (b and c) ?

Well, we can't achieve the steady state in zero time, theoretically there will be a small time during which the potentials at b and c are not the same, so there will be current through the branch bc till the potentials are the same.

And do you really think that was the intent of the problem? Is that the kind of thing you would put in a problem for beginners?

Ehm, nope I certainly don't think that was the intent of the problem. However sometimes beginners can have advanced concerns, and maybe that's what happened here with our friend @anonim .
