Use Thevenin’s theorem to find V o in the network shown in Fig. 2 Answers to Example 2: We want to find the V o for the 3 resistor, so we treat the 3 resistor as the load. Let’s use another method to find the Thevenin’s equivalent. We short the voltage sources to find the R TH After short-circuiting all the voltage source and treat 3 as load, we get Convert the Thevenin’s equivalent of the 2 sides of Fig 3 to Norton equivalent 18V 3 3 26 V 3 4 o = + × = 24V 4 2 + - V o 12V 6V 3 Fig. 2 4 2 R TH R TH = 2 // 4 = 3 4 12A 3A
