JEE Main & Advanced Physics Alternating Current / प्रत्यावर्ती धारा Question Bank Assertion and Reason

  • question_answer
    Assertion             :       A capacitor of suitable capacitance can be used in an ac circuit in place of the choke coil. Reason                 :   A capacitor blocks dc and allows ac only.

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

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

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: B

    Solution :

                We can use a capacitor of suitable capacitance as a chock coil, because average power consumed per cycle in an ideal capacitor is zero. Therefore, like a choke coil, a condenser can reduce ac without power dissipation.
