Match List-I with List-II

	List-i		List-II
a	Phase difference between current and voltage in a purely resistive AC circuit	i	$\dfrac{\pi}{2};$ current leads voltage
b	Phase difference between current and voltage in a pure inductive AC circuit	ii	zero
c	Phase difference between current and voltage in a pure capacitive AC circuit	iii	$\dfrac{\pi}{2};$ current lags voltage
d	Phase difference between current and voltage in an LCR series circuit	iv	$\tan^{- 1}\left(\dfrac{{X}_{C} - {X}_{L}}{R}\right)$
