    In order to obtain time constant of 10 s in an RC circuit containing a resistance of \[{{10}^{3}}\Omega ,\] the capacity of the condenser should be :

    A) \[10\,\mu F\]                                    

    B) \[100\,\mu F\]

    C) \[100\,0\mu F\]               

    D) \[1000\,0\mu F\]

    Correct Answer: D

    Solution :

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