    Ammeter and voltmeter readings were recorded as \[0.25\text{ }A\]and \[0.5\text{ }V\] during the experiment to determine the resistance of a given wire using Ohm's law. The correct value of the resistance is

    A)  \[0.125\Omega \]                     

    B)  \[2\,\Omega \]

    C)  \[0.75\,\,\Omega \]                     

    D)  \[0.25\,\,\Omega \]

    Correct Answer: B

    Solution :

      \[R=\frac{V}{I}=\frac{0.5}{0.25}=2\Omega \]
