Resonance - rlc series circuit

  1. Sep 11, 2014 #1
    1. The problem statement, all variables and given/known data
    in series rlc circuit maximum voltage across inductor occurs at which frequency??????????????


    2. Relevant equations



    3. The attempt at a solution
    In the series rlc circuit current through the inductor is maximum at the resonance frequency.
    But I don't know whether at resonance frequency maximum voltage occurs or not or it occurs at below or above resonance frequeny

    The equations you will fill in under 2 will actually help you give the right answer.

    @BvU,
    Can you explain in a better way

    You make a list of relevant equations under "2. Relevant equations".
    The you show what you do with them under 3. Attempt at a solution.

    That way you enable people who want to help you to give you the right assistance.

    RLC circuit

    @BvU
    Since the voltage across inductor is equal to the voltage across the capacitor in magnitude, but out of phase by 180 degrees,
    jwl*i = -(j/(wc))*i
    Here i = current, w = frequency, c = capacitor and l = inductor
    Does the maximum voltage across inductor occurs slightly below resonant frequency or or slightly above resonant frequency or at resonant frequency??????????????
    From my equation, I am unable to get the answer.

    You need an equation for the current in terms of frequency.

    If you connect a variable frequency AC generator to a series RLC circuit of emf Ug how do you calculate the current, and at what frequency is the current maximum?

    How do you get the voltage across the inductor if you know the current flowing through it?
