Transformers The efficiency of a transformer, under heavy loads, is comparatively low because copper loss becomes high in proportion to the output voltage drop both in primary and secondary becomes large iron loss is increased considerably secondary output is much less as compared to primary input copper loss becomes high in proportion to the output voltage drop both in primary and secondary becomes large iron loss is increased considerably secondary output is much less as compared to primary input ANSWER DOWNLOAD EXAMIANS APP
