The magnetization current im is a current proportional (in the unsaturated region) to the voltage applied to the core and lagging the applied voltage by 90 degree, so it can be modeled by a reactance XM connected across the primary voltage source. The core- loss current i H is a
current proportional to the voltage applied to the core that is in phase with the applied voltage, so it can be modeled by a resistance Re connected across the primary voltage source. Why these components are installed in parallel to the applied voltage source, instead of series?
