Homework Help: Oscillation frequency of circuit

  1. Apr 15, 2008 #1
    [SOLVED] oscillation frequency of circuit

    1. The problem statement, all variables and given/known data

    An L-C circuit containing an 83.0 [tex]\rm mH[/tex] inductor and a 1.50 [tex]\rm nF[/tex] capacitor oscillates with a maximum current of 0.800 A.

    Calculate the oscillation frequency of the circuit.

    2. Relevant equations
    [tex]\omega[/tex] = [tex]\frac{1}{\sqrt{LC}}[/tex]


    3. The attempt at a solution

    First I solved for omega

    [tex]\omega[/tex] = [tex]\frac{1}{\sqrt{.083 H * 1.5*10^{-9} F}}[/tex]
    [tex]\omega[/tex] = 89622.14299

    Then, since


    I just plugged in omega.

    [tex]f=2\pi*89622.14299[/tex] = [tex]563112.532 Hz[/tex]


    I typed in it, but it came back as incorrect. I looked and I can't find my mistake. I'm pretty sure I converted the units right and am using the right formulas. Can someone check to see if i did any thing wrong? Thanks.

    Are you sure about your "relevant equations" ?
