EXAMPLE
Use Thevenin to determine Vo
“Part B”
“Part A” should be as simple as possible.
After “Part A” is replaced by the Thevenin
equivalent we should have a very simple circuit
Guidelines to partition:
Open circuit voltage
The dependent sources and their controlling
variables must remain together
Options???
Constraint at super node
KCL at super node
Equation for controlling variable
Solve
Short circuit current
Setting all sources to zero and combining
resistances will yield an incorrect value!!!!
Negative resistances for some “a’s”
Solution to the problem
