Unformatted text preview: There are several ways of solving this problem. 5 Note that the 4 ohm and 2 ohm resistors are not treated as load resistors. Chapter 4, Problem 54. Find the Thèvenin equivalent between terminals ab of the circuit in Fig. 4.120. Figure 4.120 The solution manual uses left and right loops to find the open circuit V at V ab . The R th can be found with a test injection on the output. Possibly short circuit I on the output could also be used to find R th . 6 + – Chapter 4, Problem 73. Determine the maximum power that can be delivered to the variable resistor R in the circuit of Fig. 4.139. Figure 4.139 The circuit has no dependent sources making the analysis simple. Once the Thevenin equivalent is determined, the maximum power to R is easily calculated. Treat R as a load resistance and not as a part of the Thevenin circuit. 7...
