Answer / nithiyanandam

formula Kva=Kw X pf ie. 1Kva= KwX0.8 = 0.8 KW

So 1Kva=0.8 Kw.

Answer / prasath

kva is nothing but the perfect power with no load applied...
if the power enter the load then it is denoted in kw.
for ideal circuit kva=kw. but practically the power factor is the thing that determines the kw. kw= p.f.*kva.

Answer / b.janardhana rao

Simply the KVA is always depends on PF. so we want power KW is always depends on KVA and PF. the fomula is KW=KVA*PF.
