Watt is the measuring unit of power which can be measured as we know that some of the input energy is converted in to magnetic field and helps in the operation of machine as in motor a part of input is converted in to electromagnetic field which induces currents in rotor and we measure the output work in terms of KW
Kva is the unit of input that is apparent power and the measuring unit of power which cannot be measured is kvar that is reactive component of apparent power
