Watt is the product of voltage, current and power factor.
VA is the product of voltage, current and power factor.

Motor is an inductive load and operates at a power factor
less than unity. So the current drawn by it is more than the
apparent at constant power.
For a 3ph motor, P=√3*V*I*cosø where V,√3 are constants.
At constant P, I*cosø is also a constant. if pf cosø
varies, I too varies. i.e. if pf is poor (cosø reduces), I
increases. Hence rating needs to be specified in KW.

Whereas for a generator, it isn't a load. It supplies power
to a load. So power factor doesn't come into picture. Hence
its rating is specified in KVA.

sir pls send the je exam - 2008 and other model question papers..
