A balanced three-phase three-wire system is terminated with two delta-connected loads in parallel. Load 1 draws 40kVA at a lagging power factor of 0.8, while load 2 absorbs 24kW at a leading power factor of 0.9. Assume no line resistance and let Vab = 440<30° V. Assume a-b-c phase sequence. Find out the line current (in ampere) of phase-A (IaA). [Assume that the source side quantities are denoted by small letters and the quantities at the load end are denoted by capital letters]
a. 75.254<-12.46° A
b. 75.254<12.46° A
c. 43.448<-12.46° A
d. 43.448<12.46° A
