Since transformer is a static there will not be any
rotational losses it have only iron loss depend upon
voltage and copper loss depend upon current

for AC supply systems like generator, transformer rating is
done in KVA because of inductance present in AC . we don't
know load is resitive or inductive

it is independent there fore it is measured in kva

can anyone tell me can the electromagnetic waves can be reflected back?if so how &by which material it can be reflected back?please tell me so that it can help to my wireless power trasnmission device.
