Can anyone explain why the power factor of an ideal transformer cos (phi) is equal to 1??(adsbygoogle = window.adsbygoogle || []).push({});

A simple ideal transformer is formed of 2 ideal coils. The power factor of an ideal coil is 0 since phase difference between the current and the applied voltage is - π/2. Then how can the power factor of the transformer equal 1¿
