$$\mathrm{A, B}~\text{and}~\mathrm{C}$$ are voltmeters of resistance $$R$$, $$1.5R$$ and $$3R$$ respectively as shown in the figure above. When some potential difference is applied between $$\mathrm{X}$$ and $$\mathrm{Y}$$, the voltmeter readings are $${V}_\mathrm{A}$$, $${V}_\mathrm{B}$$ and $${V}_\mathrm{C}$$ respectively. Then:

 1 $${V}_\mathrm{A} ={V}_\mathrm{B}={V}_\mathrm{C}$$ 2 $${V}_\mathrm{A} \neq{V}_\text{B}={V}_\mathrm{C}$$ 3 $${V}_\mathrm{A} ={V}_\mathrm{B}\neq{V}_\mathrm{C}$$ 4 $${V}_\mathrm{A} \ne{V}_\mathrm{B}\ne{V}_\mathrm{C}$$
