... In the ideal transformer the core flux φ links both coils (i.e. the leakage flux is zero) so that the coupling coefficient k=1. We also assume that the winding resistance is zero and the hysteresis and eddy current losses in the iron core are zero. The symbol for the ideal transformer is shown in Fi ...
