  1. If Va0, Va1, Va2 are sequence components of Va and Ia0, Ia1, Ia2 are sequence components of Ia, then total 3 phase power P is given by

  2. A.
    P = Va0Ia0 + Va1Ia1 + Va2Ia2
    B.
    P = Va0Ia0 + Va1Ia1 + Va2Ia2*
    C.
    P = 3(Va0Ia0 + Va1Ia1 + Va2Ia2)
    D.
    P = 3(Va0Ia0 + Va1Ia1 + Va2Ia2*)
