Question

For the graph shown, identify curves A and B. Here X(C) is capacitive reactance and X(L) is inductive reactance. Image

X(L) = 2πfL increases linearly with frequency, whereas X(C) = 1/(2πfC) decreases inversely with frequency. Thus the decreasing curve A is X(C), and the increasing straight line B is X(L).
