  • question_answer
    Three capacitors of 3, 2 and\[6\mu F\]are connected in series with a battery of 10 V. Then charge on\[3\mu F\]capacitor will be

    A)  \[10\mu C\]                      

    B)  \[12\mu C\]

    C)  \[14\mu C\]                                      

    D)  \[5\mu C\]

    Correct Answer: A

    Solution :

                    Equivalent capacity in series \[\frac{1}{C}=\frac{1}{3}+\frac{1}{2}+\frac{1}{6}\] \[C=1\mu F\] Charge of \[1\mu F\]capacitor                 \[q=CV=1\times 10\]                 \[=10\mu C\] (Charge is same on all the capacitor in series combination).
