Answer / kiran
active power P = W1+W2
reactive power Q = 1.732(W1-W2)
so power factor cos theta = Tan-1((1.732(W1-W2)/(w1+w2))
i.e. cos theta = tan-1(reactive power/active power)

Answer / ravi gurubelli
we know W1 and W2
so real power P = W1+W2
Reactive power Q= sqrt3 (W1-W1)

Answer / rajeshwar rao
1.732(w1-w2)=Q and P=w1+w2
tan∅= (√3(W1-W2)/((W1+W2))
