IN TWO WATTMETER METHOD WE GOT W1,W2,WE KNOW V.HOW TO FIND Q????????????..

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&#8709;= (&#8730;3(W1-W2)/((W1+W2))
