a nonreference node is treated similarly to that for an independe
Specifically, the value and polarity of the dependent source determines, by inspection,
the equation for that nonreference node-KCL is not applied at that node. However,
after the nodal analysis of the circuit is completed, KCL can be applied at that non-
reference node in order to determine the current through the dependent voltage
source.
