12th Class Physics Alternating Current / प्रत्यावर्ती धारा Question Bank Assertion And Reason (MCQs) - Alternating Current

  • question_answer
    Assertion: Faraday's laws are consequences of conservation of energy.
    Reason: In a purely resistive A.C. circuit, the current lags behind the e.m.f.
     

    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: C

    Solution :

    Faraday's laws involve conservation of mechanical energy into electrical energy. This is in accordance with the law of conservation of energy. In pure resistance, the e.m.f. is in phase with the Current.
