8.17 Determine the complex power, apparent power, average power absorbed, reactive power, and power factor (including whether it is leading or lagging) for a load circuit whose voltage and current at its input terminals are given by: (a) v(t)=100 cos(377t-30°) V, i(t) = 2.5 cos(377t - 60°) A. (b) v(t) = 25 cos(2л x 10³ +40°) V. i(t)=0.2 cos(2л x 10³t - 10°) A. *(c) Vrms 110/60° V, Irms = 3/45° A. (d) Vrms (e) Vrms = == = 440/0° V, Irms = 0.5/75° A. 12/60° V, Irms = 2/-30° A.
