Answer Posted / azarudeen

kw is a real(Active) power that depends on the load that we use.
KVA is a apparent power which is the maximum power that can
be produced by source.

KVA = voltage x current

KW= voltage x current x power factor

power factor depends upon load.

Apparent Power(KVA)= real power(KW) + reactive power(KVAr)
