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

  • question_answer
    ASSERTION: A capacitance can be broken by placing large amount of charge on it.
    REASON: After breakage potential, capacitor is destroyed.

    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 :

    When large amount of charges are placed on capacitor a high potential difference is established between its conducting components. If this Potential difference is above what is called breakage potential, an electric discharge results, destroying the capacitor. If the capacitor contains an insulator between its conducting components, the insulator will be burnt at the atomic/molecular level. A capacitor subjected to voltage exceeding the breakage potential cannot be recovered. It should be discarded and replaced.
