the voltage leads the current if $X_L > X_C$

(B) In a series $L-C-R$ circuit,the total voltage $V$ is given by the phasor sum of the voltages across the resistor,inductor,and capacitor.The phase angle $\phi$ between the voltage and current is given by $\phi = \tan^{-1} \left( \frac{X_L - X_C}{R} \right)$.If $X_L > X_C$,then $\phi$ is positive,which means the voltage leads the current.If $X_L Therefore,the voltage leads the current when $X_L > X_C$.
