  • question_answer
    A capacitor in an LC oscillator has a maximum potential difference of 17 V and a maximum energy of \[160\,\mu J\]. When the capacitor has a potential difference of 5V and an energy of \[10\,\mu J,\] what is the energy stored in the magnetic field?

    A) \[10\,\mu J\]

    B) \[150\,\mu J\]    

    C) \[160\,\mu J\]

    D) \[170\,\mu J\]

    Correct Answer: B

    Solution :

    [b] \[{{U}_{e}}+{{U}_{m}}=160\,\,\,\,\,\,\,\,\therefore \,{{U}_{m}}=160\,-{{U}_{e}}=160-10\] \[=150\,\mu J.\]
