Yes, Sir. Perfectly right. Those are the only relevant nodes you have because the third one is is ground and for that we know V=0

oh kk. sometimes im not so sure which to read, very confusing. erm the current source I2 is not a supernode right?

I never heard about the concept of supernode, can you explain?
anonymous

omg i think its not supernode. its supermesh. anyway, supernode exists when an ideal voltage source appears between any 2 nodes, while supermesh is when an ideal current source appears between 2 meshes.

First time I hear that. Thanks for explaining. Can you settle the equations for resolution or you need help?

i got my Va = -2.55V, Vb = 4.03V so if the question asked for voltages across each resistive element, the question is asking for the voltages across all the resistors?

There it goes

Voltages accross the resistors are Va for R1, Va-Vb for R3 and R4 and Vb for R2 and R5

Good luck with your test

wow thx alot. your working is much shorter.

Same concept as by meshes but using voltages and the inverse of the resistance (conductance)
