    If an inductor is connected across an ac source and suppose the frequency of the source is doubled, then t he inductive reactance of the inductor is also doubled. The inductive reactance (XL) is the t he opposition to current flowing through a coil in an AC circuit, the impedance measured in Ohms and can be calculated with the following formula:

    XL=2*pi*f*L,

    where f is the frequency. So, if the frequency is doubled than also the inductive reactance is doubled.
