I'll be happy for some help here.
Thanks. :redface:

For now, I am only focused on the magnitude.
So am I. :smile: You have added I₁ + I₂ without regard for their different angles.
 
oops.. :) but still, S1 and V1 are similar in phase, aren't they? And since that's the case, S/V yields magnitude only (on the real axis). Same for both loads. And since the phase becomes 0 for both I1 and I2 (which is wrong obviously, but I cannot figure out where exactly I miss a thing here) so I can add I2 to I1.
That's probably my problem here. Any idea?
 
What does "similar in phase" mean exactly http://img820.imageshack.us/img820/9631/icon5j.gif

The details are that one load has a leading pf and the other a lagging pf.
