12th Class Physics Electrostatics & Capacitance Question Bank Assertion And Reason (MCQs) - Electric Potential and Capacitance

  • question_answer
    ASSERTION: A capacitor can be given only a limited quantity of charge.
    REASON: Capacitor is an arrangement which can store sufficient quantity of charge.

    A) If both assertion and reason are true and reason is the correct explanation of assertion.

    B) If both assertion and reason are true and reason is not the correct explanation of assertion.

    C) If assertion is true but reason is false.

    D) If both assertion and reason are false.

    E) If assertion is false but reason is true.

    Correct Answer: B

    Solution :

    The quantity of charge that can be given to a capacitor is limited by the fact that every dielectric is limited by the dielectric strength of medium between the plates. The dielectric strength is a maximum value of electric field that it can tolerate without breakdown. Beyond this field the dielectric no more behaves as dielectric but it conduct electricity.
