Current Electricity Question 11
Question 11 - 2024 (27 Jan Shift 2)
Three voltmeters, all having different internal resistances are joined as shown in figure. When some potential difference is applied across $\mathrm{A}$ and $B$, their readings are $V_{1}, V_{2}$ and $V_{3}$. Choose the correct option.
(1) $V_{1}=V_{2}$
(2) $V_{1} \neq V_{3}-V_{2}$
(3) $V_{1}+V_{2}>V_{3}$
(4) $V_{1}+V_{2}=V_{3}$
Show Answer
Answer: (4)
Solution:
From KVL,
$V_{1}+V_{2}-V_{3}=\mathbf{0} \Rightarrow V_{1}+V_{2}=V_{3}$
