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

  • question_answer
    The ratio of energy stored in a capacitor and energy dissipated during charging a capacitor with a source:

    A) 1 : 1                             

    B) 1 : 2      

    C) 2 : 1                             

    D) 1 : 3

    Correct Answer: A

    Solution :

    (a) 1 : 1 Half of the energy provided by the source is dissipated during charging a capacitor and other half stored in capacitor. \[\therefore \,\,\frac{Energy\text{ }stored\text{ }in\text{ }a\text{ }capacitor}{Energy\text{ }dissipated\text{ }during\text{ }charging\text{ }a\text{ }capacitor}=\frac{1}{1}\]
