Answer / arun

manoj cos(phi)=kw/kva ur formula is wrong

Answer / sachin lakhe

when the power factor decreases ,load kw will increase
formulla KW=KVA/PF.
for given voltage level..
p=V*I cos(theta)

now see when bill comes by MAHADISCOM they consider ur Max
demand and used KW.
f power factor is down will increase Demand

Answer / sanjay kumar

we know that P=VICOS(theta)
cos(theta)is power factor which directly propational to
power (P) by this it is very clear that if P.F will less
then power will be less
