JEE Main & Advanced Physics Alternating Current / प्रत्यावर्ती धारा Question Bank ac Circuits

  • question_answer
    A series ac circuit consist of an inductor and a capacitor. The inductance and capacitance is respectively 1 henry and \[25\mu F.\] If the current is maximum in circuit then angular frequency will be                                                 [RPMT 1999]

    A)            200

    B)            100

    C)            50  

    D)            200/2\[\pi \]

    Correct Answer: A

    Solution :

                       Current in LC circuit becomes maximum when resonance occurs. So            \[\omega =\frac{1}{\sqrt{LC}}=\frac{1}{\sqrt{1\times 25\times {{10}^{-6}}}}=\frac{1000}{5}=200\,rad/\sec \]
