Some electric circuits with an A.C. source is given in List-I. In List-II instantaneous current and average power delivered by A.C. source are given. The Match List-I with List-II.

	LIST-I		LIST-II (Can be distinguished by)
P)		1)	$I=\frac{\sqrt{10}}{4}\sin [\omega t+\frac{\pi }{4}-{\tan }^{-1}\left(\frac{1}{2}\right)]$ $P=\frac{15}{4}$ watt
Q)		2)	$I=2\sqrt{2}\cos \omega t,P=200$watt
R)		3)	$I=\sin \omega t,P=5$watt
S)		4)	$I=\frac{1}{\sqrt{2}}\sin (\omega t+\frac{\pi }{4}),P=\frac{5}{2}$watt
		5)	$I=\frac{\sqrt{10}}{4}\sin (\omega t+\frac{\pi }{4}-{\tan }^{-1}\left(2\right)),P=\frac{7}{2}$ watt
