what is the deference between watt and KVA

Answer Posted / niharika

both are the units of power..
KVA is the apparent power i.e V*I irrespective of the power factor on which it is working.Eg.transformer can work in lagging and leading pf.
while KW is the active power i.e V*I*pf, it is the actual output power which is obtained for doing specified mechanical work. Eg. motor
