    If a voltmeter of resistance 1000 \[\Omega \] is connected across a resistance of 500 \[\Omega \]  in the given circuit, then the reading of voltmeter will be

    A)  1 V  

    B)  2 V  

    C)  6 V

    D)  4 V

    Correct Answer: D

    Solution :

    Total current through the circuit                 \[i=\frac{10}{\frac{1000}{3}+500}=\frac{3}{250}A\] \[\therefore \] Voltmeter reading \[{{i}_{V}}\times {{R}_{V}}=\frac{2}{3}\times \frac{3}{250}\times 500=4\,V\]
