    there are a couple question on a lab report that I don't quite understand:

    Thanks:)

    The question is asking about Xi (probably the reactance of an inductor). Your circuit has no hint of an Xi, regardless of what it is.

    Assuming Xi is an inductor.

    When,

    | j\omega L| = |\frac{-j}{\omega C}|

    \omega_{o} = \frac{1}{\sqrt{LC}}

    Where \omega_{o} = 2 \pi f_{o} is the resonance frequency in rad/s. (f_{o} is the resonant frequency in Hz)
