12th Class Physics Electrostatics & Capacitance Question Bank MCQ - Electrostatic Potential and Capacitance

  • question_answer
    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 :

    (c) 9090 Let n capacitors are connected in parallel, \[{{C}_{parallel}}=nC\] We know that, \[Q={{C}_{parallel}}V\] \[1=\left( nC \right)\times 110\] \[1=n\times 1\mu F\times 110\] \[n=\frac{1}{110\times {{10}^{-6}}}=\frac{{{10}^{6}}}{110}\] \[n=9090\]
