Chapter Problem 17P Step by solution Step 10 Refer to Figure P1 the text book Disconnect the resistance and redraw the circuit diagram as shown Figure 1. +10V Figure Step 10 Calculate the value of the Thevenin's voltage at node 1. 1.2k =(10) 1.2k =(10) 2.2k =(10)(545.45 m) =5.454 V the value of the voltage is 5.454 V Step 10 Calculate the value of the Thevenin's voltage VTH2 11k =(10) 11k =(10) 20.1k =5.473 V the value of the voltage is 5.473 V Step 10 Consider the circuit in Figure to calculate the Thevenin's resistances 5 Step 10 Calculate the value the Thevenin's resistance (1k)(1.2k) 1.2k+1k 1.2k 2.2 the value of the resistance is Step 6 of 10 Calculate the value of the Thevenin's resistance RTH2 (11k)(9.1k) 11k+9.1k 20.1 the value of the resistance Comments (2) Anonymous Why did you drop the in the second calculation? shouldn't it just be 4.98 ohm? Anonymous cuz denominator square of bro Step 10 Draw the two Thevenin's equivalent circuits are shown Figure 3. 4.98 kΩ 2 5.454 V 5.473V Figure 3 Step 10 Draw the equivalent circuit with resistor shown in Figure 4 2 kΩ 4.98 kΩ 2 + 5.473V Figure 4 Step of 10 Calculate the current through the resistor 5.473-5.454 0.018 7.5254 k the value of the current Comments (1) Anonymous Current should be 2.3918x10^-6 Step 10 of 10 Calculate the value voltage across the resistor Substitute 2.5247 for and for =5.0494 mV the value of the voltage across the resistor R. 5.0494 mV
