I tried using your suggestion to solve the problem, it ended up looking like this:
(in a step by step version)
\begin{bmatrix}
A_1 & -A_2 & 0\\
A_1 & 0 & -A_3\\
1 & 1 & 1
\end{bmatrix}
\begin{bmatrix}
x_1\\
x_2\\
x_3
\end{bmatrix}
=
\begin{bmatrix}
B_1\\
B_2\\
B_3
\end{bmatrix}...
You pointed it right, there is something wrong with the system. I went back to the question and found that the data given is wrong. The sum of the currents in the node in question is not equal to zero, therefore we have this problem.
I found this question in a test that is now 2 years old, and...
Homework Statement
The problem is rather simple. A set of linear equations, in the form V=Z*I, is given to represent a circuit in the frequency domain. The values for the V and I vectors are given and i have the Z(impedance) matrix written in function of the Z1, Z2, Z3,...,Zn variables?
In a...
