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?

Answer»

At `=(pi)/(2omega)`, instantaneous power supplied by source is negative.
From `0lttlt(2pi)/(3omega)`, AVERAGE power supplied by source is positive.
At `t=(5PI)/(6omega)`, instantaneous power supplied by source is negative.
If `omega` is increased slightly, angle between the two PHASORS decreases.
