For a RLC series circuit , phasors of current i and applied voltage V`=V_(0)sin omegat` are shown in diagram at t=0, which of the following is/are CORRECT?

A

At `=(pi)/(2omega)`, instantaneous power supplied by source is negative.

B

From `0lttlt(2pi)/(3omega)`, average power supplied by source is positive.

C

At `t=(5pi)/(6omega)`, instantaneous power supplied by source is negative.

D
