    How many\[1\mu F\] capacitors must be connected in parallel to store a charge of 1 C with a potential of 110 V across the capacitors?

    A)  990           

    B)  900

    C)  9090          

    D)  909

    Correct Answer: C

    Solution :

    Charge \[q=nCV\] \[1=n\times 1\times {{10}^{-6}}\times 110\] \[n=\frac{1}{110\times {{10}^{-6}}}\] \[n=\frac{1000000}{11}\] < 9090
