    A capacitor of capacitance 500\[\mu F\] is charged at a steady rate of 100\[\mu C\,{{s}^{-1}}\]. The potential difference across the capacitor will be 10V in time

    A)  25 s                                      

    B)  50 s

    C)  75 s                                      

    D)  100 s

    Correct Answer: B

    Solution :

                    For the potential difference of 10 V, charge required by capacitor \[q=CV\] \[q=500\times {{10}^{-6}}\times 10=5\times {{10}^{-3}}C\] \[\therefore \] Required time\[=\frac{5\times {{10}^{-3}}}{100\times {{10}^{-6}}}\]  \[=50s\]
