As per the given graph, choose the correct representation for curve $A$ and curve $B$.
{Where $X_C$ = reactance of pure capacitive circuit connected with A.C. source; $X_L$ = reactance of pure inductive circuit connected with A.C. source; $R$ = impedance of pure resistive circuit connected with A.C. source; $Z$ = impedance of the LCR series circuit}
Answer: (D) $A=X_C,\ B=X_L$
$X_C=\dfrac{1}{2\pi fC}$ falls as $\dfrac1f$ (curve A) and $X_L=2\pi fL$ rises linearly from zero (curve B).
