The iron loss of a transformer is nearly constant with load because
Answer: A
Correct answer: the core flux is fixed by the applied voltage
From \( E = 4.44fN\Phi_m \), the peak flux is set by the applied voltage and frequency, both of which stay constant as load varies. Hysteresis and eddy current loss depend on that flux, so the core loss barely changes from no load to full load. This is why it is treated as a constant loss when efficiency is computed.
