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

    A) 1 V                              

    B) 2 V             

    C) 6 V                              

    D) 4 V             

    Correct Answer: D

    Solution :

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