Problem 1. (a) To find the Thevenin equivalent resister R T , the current source and the load resistor are replaced by open circuits, and the voltage sources are replaced by short circuits. R T = 1 1+ 1 1+ 1 1+1 +1 = 3 8 [ ] (=0.375 [ ]) To find the Thevenin voltage, a superposition method is used.
