Vedclass · Answer

(D) In a purely capacitive circuit,current $I$ leads voltage $V$ by $90^{\circ}$. Thus,$A$ matches with $I$.In a purely inductive circuit,voltage $V$ leads current $I$ by $90^{\circ}$. Thus,$B$ matches with $IV$.In an $LCR$ series circuit at resonance,inductive reactance $X_L$ equals capacitive reactance $X_C$ $(X_L = X_C)$,making the circuit purely resistive. In a purely resistive circuit,voltage $V$ and current $I$ are in phase. Thus,$C$ matches with $II$.In a general $LCR$ series circuit,the voltage $V$ leads or lags the current $I$ by a phase angle $	heta$. Thus,$D$ matches with $III$.Therefore,the correct matching is $A-I, B-IV, C-II, D-III$. The correct option is $(D)$.

List-$I$	List-$II$
$A$. Purely capacitive circuit	$I$. $I$ leads $V$ by $90^{\circ}$
$B$. Purely inductive circuit	$II$. $I$ and $V$ are in phase
$C$. $LCR$ series at resonance	$III$. $V$ leads $I$ by angle $\theta$
$D$. $LCR$ series circuit	$IV$. $V$ leads $I$ by $90^{\circ}$
