dear Help, I m trying to calculate the power: when using the formula P=1/2Re(VI*) 1/2RE(77325.2+j3148.84)(j119.926= -188814 but when i use P=VsrIsr+VsiIsi = 77325.2+(j3148.84xj119.926)= -300303 where do i go wrong?

Thank you for your help.

Sorry made a mistake in calculation so i have : V20(0.75+J0.05)=67071+J30 V20=91.6872+J33.875 V20/Z4=I I=91.6872+J33.875/-J5 I=-6.7775+J18.3374
