Explanation Given data: Refer to Figure given in the textbook. Calculation: In the given circuit of Figure, the Thevenin resistance is determined by removing the variable resistor R o and find the equivalent resistance across it. In the given circuit, make the voltage source as short circuit and the current source as open circuit to find the Thevenin resistance. Figure 1 shows the modified circuit diagram. PSPICE Simulation: Draw the circuit diagram of Figure 1 in PSPICE as shown in Figure 2. Save the circuit and provide the Simulation Settings as shown in Figure 3. Now run the simulation and the results will be displayed as shown in Figure 4 by enabling “Enable Bias Current Display” icon. From Figure 4, the Thevenin resistance is calculated using Ohm’s law as follows. R Th = 1 V 400 μ A = 1 V 400 × 10 − 6 A { ∵ 1 μ = 10 − 6 } = 2500 × 10 − 3 × 10 3 Ω = 2.5 k Ω { ∵ 1 k = 10 3 } In the given circuit of Figure, the Thevenin resistance R Th is equal to the variable resistor R o at maximum power transfer. Therefore, R Th = R o = 2.5 k Ω Draw the given circuit diagram in PSPICE as shown in Figure 5 with variable resistor R o = 2.5 k Ω . Save the circuit and provide the Simulation Settings as shown in Figure 6. Now run the simulation and the results will be displayed as shown in Figure 7 by enabling “Enable Bias Power Display” icon. From Figure 7, the maximum power delivered to the variable resistor R o (R6 2
