Find the node voltages in the circuit in Fig. 17.4-6. Prepare the network graph with the
reference direction for currents as marked in the figure.
SOLUTION
The network contains a VCCS. The controlling variable is identified as v
x
v
2
, the branch
voltage of Branch-2. The dependent source output is then 21v
2
. The oriented graph of
the network is shown in Fig. 17.4-7. The passive branches are numbered first, followed by
the dependent source and independent current sources.
The A matrix is:
Note that the branch representing the output port of the dependent source
appears as the last column of A
p
.
The Y
p
matrix will contain ...
