In basic electrical, when heat is produced, we say work is
done. kW is a real or active power because it causes radiation,
dissipation, and/or mechanical motion and kVA produces both heat
and inductive / capacitive fields.
Example: In a motor, kW is consumed in the resistance of the
motor winding and is causing heating of the motor winding
only. And, if kVA be not there then motor will not rotate
because kVA is the power consumed in the motor winding
resistance as well as producing the magnetic field in the
rotor winding.
