Question

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 $L C R$ series circuit }

The formula to calculate the inductive reactance is

$X_{L} = ω L . . . (1)$

The formula to calculate capacitive reactance is

$X_{C} = (\frac{1}{ω C}) . . . (2)$

As can be seen from equation (1), the inductive reactance varies directly with the frequency and equation (2) indicates that capacitive reactance varies inversely with the frequency.

Hence, curve $A$ represents the capacitive reactance and curve $B$ represents the inductive reactance.
