$C$

Vedclass · Answer

(C) In a series $LCR$ circuit,the circuit is inductive when the inductive reactance $X_L$ is greater than the capacitive reactance $X_C$ $(X_L > X_C)$.Looking at the graph:At point $A$,$X_C > X_L$,so the circuit is capacitive.At point $B$,$X_C = X_L$,so the circuit is purely resistive (resonance).At point $C$,$X_L > X_C$,so the circuit is inductive.Therefore,the correct point is $C$.

The figure shows the variation of $R$,$X_L$,and $X_C$ with frequency $f$ in a series $LCR$ circuit. For which frequency point is the circuit inductive?
