The voltmeter is shown in the circuit reads:

• A. 1.2 V
• B. 12 V
• C. 2.4 V
• D. 24 V

Answer: (B)

Total resistance in the given circuit
R = (250 + 250)MΩ = 500 MΩ
Current I = V/R = 24/(500 × 103)
Now the Voltage in the voltmeter
= \dfrac{{24}}{{500 \times {{10}^3}}} \times 250 \times {10^3}
V = 12 V
