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