Answer / sudhanva

If the angle between current phasor and voltage phasor becomes equal to zero then such circuits are called pure resistive and if that angle becomes equal to 90 , it is pure inductive and if the angle becomes -90 , it is pure capacitive. Here current phasor is taken as reference..

how can i determine the KVA/MVA rating of transformer precisely?? is there any standard test?????
