 For an inductor, the impedance (or more specifically, the reactance) XL is imaginary and can be represented as a line along the positive y-axis of the 2-D plot. The reactance of the inductor also depends upon the frequency and is given as:  For an inductor, the impedance (or more specifically, the reactance) XL is imaginary and can be represented as a line along the positive y-axis of the 2-D plot.
