Physics for IGCSE & O level - Magnets And Currents (Section 10 - No. 43)
The efficiency of a transformer is primarily reduced by:
The frequency of the AC supply
The number of turns in the primary coil
The resistance in the core and the coils
The size of the core
Explanation
Resistive heating in the core and coils accounts for most of the losses.
