  • question_answer
    How much charge should be placed on a capacitance of 25 pF to raise its potential to \[{{10}^{5}}V?\]

    A) \[1\mu C\]                     

    B) \[1.5\,\mu C\]

    C) \[2\mu C\]                     

    D) \[2.5\mu C\]

    Correct Answer: D

    Solution :

    (d) \[2.5\mu C\] As \[q=CV=25\times {{10}^{-12}}\times {{10}^{5}}=2.5\mu C\]
