Explanation Given data: The internal resistance of voltmeter is 100 k Ω . Refer to Figure given in the textbook. Calculation: In the given circuit, the voltage source 36 V with series resistance 12 k Ω is converted into current source 3 mA with the parallel resistance 12 k Ω using source transformation method as shown in Figure 1. That is, the current source is calculated by using Ohm’s law as follows. current source = 36 V 12 k Ω = 36 V 12 × 10 3 Ω { ∵ 1 k = 10 3 } = 3 × 10 − 3 A { ∵ 1 A = 1 V 1 Ω } = 3 mA { ∵ 1 m = 10 − 3 } Figure 1 shows the modified circuit diagram. In Figure 1, the two current source are in opposite direction. Therefore, the resultant current source is calculated as follows. current source = 18 mA − 3 mA = 15 mA Since the current source is positive, then the current direction of current source directed upwards as shown in Figure 2. In Figure 1, the resistor 12 k Ω and 60 k Ω are connected in parallel. Therefore, the equivalent resistance for parallel connection is calculated as follows. 12 k Ω | | 60 k Ω = 12 k Ω × 60 k Ω 12 k Ω + 60 k Ω = 10 k Ω Figure 2 shows the reduced circuit diagram
