Read the Thevenin-Norton class notes.
For the circuit shown,
- R1 = 390 Ω
- R2 = 180 Ω
- R3 = 470 Ω
- R4 = 180 Ω
- VS = 18 V
- γ = 0.02 S

Find the Thevenin equivalent of the circuit at the port defined by the nodes a and b.
(Recall that the "short-cut" method cannot be used to find equivalent resistance when the circuit has dependent sources.)
