D.C. component of the waveform shown below is—

1. 0.5 A
2. 1.38 A
3. 3.18 A
4. 6.36 A

Correct Option: C

D. C. component =	1			f(t) dt
	T		_T

=	1			^π			^2π	0.dt
	2π						_π

=	10	–	cos t	^π	+ 0
	2π			₀

=	10	– cos	2π	π + cos 0
	2π		2π

=	10		1 + 1
	2π

=	10
	π

=	10
	π .	2π
		2π

=	10	= 3.18 amp.
