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. If `omega` is increased slightly, angle between the two phasors decreases. |
