I have the following circuit (see Picture 1) on which I have to apply the node voltage method:
I have to use the steps which are described in the script that the prof. gave me.
The first step is to change the power supply with the series resistor \$R_2\$ into an current supply with the resistor connected parallel (see Picture 2) and to mark all currents in the circuit.
The second step is to define the linearly independent equations for the nodes \$1\$ and \$2\$. This can also be seen in Picture 2.
My question is: Are the equations that I wrote correct? Because later, when I have to write the resulting system of equations for all node voltages I get \$I_{q_1}\$ and \$I_{q_2}\$ in the same vector component.
