Question 167: 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

$$V_1+V_2>V_3$$
