Question:
Three voltmeters, all having different internal resistances are joined as shown in figure. When some potential difference is applied across A and B, their readings are $V_1$, $V_2$ and $V_3$.
Choose the correct option.

- $V_1 = V_2$
- $V_1 \neq V_3 - V_2$
- $V_1 + V_2 > V_3$
- $V_1 + V_2 = V_3$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Applying Kirchhoff’s Voltage Law (KVL) across the loop: \(V_1 + V_2 - V_3 = 0 \implies V_1 + V_2 = V_3.\)
The Correct answer is: $V_1 + V_2 = V_3$
