Hi, I have this example. I'd like to use the Cramer's rule so I tried to construct the conductance matrix. But I'm not sure I'm doing it right. I need to determine V2, V3 and currents through all resistors. Thank you for your help!

[G1+G2+G5+G7 -G5 0] [V10] [Iz1-Iz2]
[-G5 G3+G5+G6 -G6] [V20] = [0]
[0 -G6 G4+G6+G7] [V30] [Iz2]

 

I figured it out myself! You can delete this thread. Thank you!

 

Hello,

Show us your results so we can see if they are correct.

Hello, I made a mistake in the conductance matrix (the zeros should be -G7...I hope). I tried to use the mesh current method on the same circuit and the results seem to be correct now.
