    A voltmeter is connected to resistance R in parallel as shown in figure. The value of R for which reading in voltmeter is 2 V is

    A)  \[8\,\,\Omega \]            

    B)  \[4\,\,\Omega \]

    C)  \[2\,\,\Omega \]            

    D)  zero

    Correct Answer: C

    Solution :

    Reading in voltmeter is 2V. Potential difference across R is 2 V which is possible when \[\operatorname{R} =2\,\,\Omega \],
