builder_user said:Some of your results are similar to mine but some of them are completely different.
I think your results are correct so I'll use them.
You should check your math to see if you can't arrive at the same results; it's important to be able to work these sorts of problems before things get even more complicated! Besides, you never know, I might have mucked up somewhere!
P = e * conjugate(I) = 0.0156 - j1.117 W ;
I can't get this result
You may need to hang on to more decimal places in your intermediate results.
e = 8.0670 - j15.9699 V
I = 0.0561 + j0.0274 A
e*conj(I) = (8.0670 - j15.9699)*(0.05614 - j0.02738) W
= [8.0670 x 0.05614 - (-15.9699 x -0.02738)] + j[-15.9699 x 0.05614 + 8.0670 x -0.02738]
= [0.4529 - 0.4373] + j[-0.2209 + -0.8966]
= 0.0156 - j1.117
