Hi, please help me with this question..
Two balanced star-connected loads of (8+j5) ohm/phase and (6-j2) ohm/phase are supplied by a three-phase source at a line-to-line voltage of 440 V. Find
a. the line current drawn by each load
b. total line current supplied by the source
c. real, reactive, and complex power absorbed by each load
d. real, reactive and complex power delivered by the source.
Ok, I did the part a, and got the answer for line current by each load are, 26.92\(\angle -32\) for (8+j5) and 40.16 \(\angle18.45\) for (6-j2).. and now, I'm stuck with part b onwards.. do I just add up the current from each load to get the total current supplied by the source?? can anyone enlighten me how to approach part b onwards? thanks
