Simple - Inductance Question

  1. Oct 6, 2008 #1
    1. The problem statement, all variables and given/known data

    An AC generator produces a voltage of 230<45º volts. It is connected across an impedance of 17.4<-33º ohms.

    The supply frequency = 50Hz


    I got my assignment back and this question wrong, maybe you can guide me, please because I’m not sure entirety. Help is appreciated.

    Question: Calculate the value of inductance that will make the circuit become series resonant at 50Hz?


    2. Relevant equations

    1/2π fc = 2 π fl

    3. The attempt at a solution

    I= 17.4 sin33 = 9.47
    C= 1/2 π (50x9.47) = 3.36x10^-6
    Would it be: 2 π fl > 2 π(50) = 314 ?

    Please don't double post. Also, this is not an Advanced physics problem. See solution under your EE post.
