From that, I calculated the complex power of load B to be [ -2.42 + j6.33 ] my power factor calculation I am using inverse tan ( Q/P) , where Q i got -1.91 & P to be 5.559, which I got from my total complex power. If that helps. But I am calculating a negative power factor, so i am curious where I went wrong, Thank you!
