Please check out below figure.

• A. 5 Ω
• B. 10 Ω
• C. 2 Ω
• D. 1 Ω

Answer: (B)

From the figure it can be concluded that the voltmeter reads 5 volts as shown in the figure below. Based on the voltmeter and ammeter readings in the measuring network, determine the value of the resistor R Here Current I = 1/2 A = 0.5 A Voltage V = 5 V R = V/I = 0.5/5 R = 10Ω
