Question 241: Current Electricity

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.

Accepted Answer

From KVL,
$\mathbf{V}_{\mathbf{1}}+\mathbf{V}_{\mathbf{2}}-\mathbf{V}_{\mathbf{3}}=\mathbf{0} \Rightarrow \mathrm{V}_1+\mathrm{V}_2=\mathrm{V}_3$

Answer

$V_1=V_2$

Answer

$V_1 
eq V_3-V_2$

Answer

$V_1+V_2=V_3$

Answer

$V_1+V_2>V_3$
