    The value of resistance is \[10.845\Omega \] and the value of current is 3.23 A. The potential difference is 35.02935 volt. Its value in significant number would be

    A) 35V

    B)  35.0V

    C)  35.03V

    D)  35.029V

    Correct Answer: B

    Solution :

    [b] The significant number in the potential, \[V=iR\]; should be the minimum of either / or R. So corresponding to\[i=3.23\text{ }A\], we have only three significant numbers in\[F=35.02935\text{ }V\]. Thus the result is \[V=35.0\text{ }V.\]
