Supernodes can be more complex
Identify all nodes, select a
reference and label nodes
Nodes connected to reference through
a voltage source
Voltage sources in between nodes
and possible supernodes
EQUATION BOOKKEEPING:
KCL@ V_3, KCL@ supernode,
2 constraints equations
and one known node
KCL@V_3
KCL @SUPERNODE
(Careful not to omit any current)
CONSTRAINTS DUE TO VOLTAGE SOURCES
5 EQUATIONS IN FIVE UNKNOWNS.
