Transformers No-load on a transformer is carried out to determine magnetising current and loss magnetising current copper loss efficiency of the transformer magnetising current and loss magnetising current copper loss efficiency of the transformer ANSWER DOWNLOAD EXAMIANS APP
Transformers The efficiency of a transformer, under heavy loads, is comparatively low because 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 copper loss becomes high in proportion to the output ANSWER DOWNLOAD EXAMIANS APP
