Homework Help: Resonant Frequency-Assignment 2_PLS_Help

  1. Nov 23, 2013 #1
    1. The problem statement, all variables and given/known data
    The Variables
    Z=√R²+(ωL-1/ωC)² where ω= 2pif

    2. Relevant equations

    I never did this kind of assignment before so I am asking for some tips how can I work out the DZ/DC and plot it on graph i mean the Impedance and for Capacitor. Please find my attached Assignment paper and help me to complete it. I'd really appreciate it if you can save me.

    3. The attempt at a solution
    I tried to put some values for R=10kΩ,L=0.05,f=5Hz then I put it in this formula ω=1/√LC to find Capacitor value then I found C=0.01pF.
    after that I tried to work out the impedance by this formula Z=√R²+(ωL-1/ωC)²=9.50,,then I ploted on a graph for Z and C then i dont know how to work out minimum value for C?? and how should I do it?
