Example: -1 Using the Thevenin’s theorem, find the current i through R= 2Ω. Refer Fig.1. Fig.1 PL SOLUTION Figure 2 Since we are interested in the current through the resistor is identified as circuit B and the remainder as circuit A. After removing the circuit B, circuit A is as shown in Fig. 3. Figure 3 To find Rt, we have to deactivate the independent voltage source. Accordingly, we get the circuit in Fig. 4. Fig. 4 Referring to Fig. 4, Thus, we get the Thevenin’s equivalent circuit which is as shown in Fig.5. Figure 5 Figure 6 Reconnecting the circuit B to the Thevenin’s equivalent circuit as shown in Fig. 6, we get Example: -2 (a) Find the Thevenin’s equivalent circuit with respect to terminals a-b for the circuit shown in Fig. 1 by finding the open-circuit voltage and the short–circuit current. (b) Solve the Thevenin resistance by removing the independent sources. Compare your result with the Thevenin resistance found in part (a). Figure 1 SOLUTION Figure 2
