    What should be the capacity of capacitor of R-C circuit, in which the value of resistance is 10\[\Omega \] to become the value of time constant 10? 

    A)  \[10\mu F\]

    B)  \[100\mu F\]

    C)  \[1000\mu F\]

    D)  \[10,000\mu F\]

    Correct Answer: D

    Solution :

     Time circuit\[\tau =RC\] or        \[C=\frac{\tau }{R}=\frac{10}{{{10}^{3}}}\] \[={{10}^{-2}}F=10000\mu F\]
