Voltage divider

  1. Jan 26, 2010 #1
    1. The problem statement, all variables and given/known data

    The problem deals with a circuit that has a voltage divider composed of an inductor L and a capacitor C in series connected to a node, one end is an open circuit with the output voltage and the other end is connected to a resistor R that is connected to ground.

    Find the response ( Vout/Vin ) versus frequency.


    2. Relevant equations



    3. The attempt at a solution


    I found the amplitude of V out by finding V out = (Zr / (Zr + Zc + Zl) )*Vin and multiplying V out by its complex conjugate and taking the square root. This got me to |Vout| = R * Vin / ( R^2 + (wL-1/wC)^2)^.5

    From that equation I see that V out is 0 at 0 frequency, and then also 0 at infinite frequency but don't know anything about the middle. Am I even on the right track?

    Thanks for the help
