Answer / chad
KW=1.732* V*I*cos@
KVA=1.732*V*I
We can see the equation the kw is change by load,but kva power is not change by load.thats is

Answer / deepak
tx o/p limited by heating hence losses
and losses depend apn V, I only not on load pf
so rating in volt-amp.not in watt.watt mean active
powr depend apn pf also
