Answer / prof. nazar m. karyar
KVA is the apparent power of an electrical load (refer to
the power triangle diagram),it means the voltmeter reading
times the Ammeter reading of the electrical load. KWh is the
electrical energy consumed by the electrical in certain
hours of time

Answer / laxman murmu
kva means kilo volt ampere.the transformer,alternator rating
are measured by kva.khw means kilo watt hour.it is the unit
of electrical energy.

Answer / keshav
Both are unites of power.
KWH=KVA X power factor.
or KWH=KVA X PF
If power factor is not given, it is assumed to be 0.8
KWH is the actual power that is available and can never be more than KVA.
For pure resistive load, KWH=KVA as Pf is unity in this case.
