Homework Help: Help me ! [Inductance]

  1. Nov 26, 2008 #1
    help me plz! [Inductance]

    1. The problem statement, all variables and given/known data
    an experiment to determine the inductance and internal resitance of an inductor in a series LCR circuit.
    I am proved with an a.c. power supply, an inductor, a capacitor substitution box, a resistor and an a.c. voltmeter

    2. Relevant equations
    how can i find the resonace frequency, inductance and the internal resistance of the inductor?

    3. The attempt at a solution
    I was suggested to use graphical method to find out the resonance frequency
    but i don't know how can i do it.

    At resonance the sum of the inductive and capacitive impedances = 0.

    This occurs at the frequency f = 2pi sqrt(1/LC).
