    how do i find the capacitive reactance if the total impedance of this circuit is 100 [​IMG]. The value of the resistor is 100 [​IMG], and the inductive reactance is 100 [​IMG]????

    Hmm, so elements are connected in Series RLC??

    The total impedance of a series LC circuit approaches zero as the power supply frequency approaches resonance.
    So in resonance the impedance will by equal R.
    Now you should have no problems to find Xc
