Transformers Which winding in a transformer has more number of turns? Primary winding Low voltage winding Secondary winding High voltage winding Primary winding Low voltage winding Secondary winding High voltage winding ANSWER DOWNLOAD EXAMIANS APP
Transformers The efficiency of a transformer, under heavy loads, is comparatively low because secondary output is much less as compared to primary input voltage drop both in primary and secondary becomes large copper loss becomes high in proportion to the output iron loss is increased considerably secondary output is much less as compared to primary input voltage drop both in primary and secondary becomes large copper loss becomes high in proportion to the output iron loss is increased considerably ANSWER DOWNLOAD EXAMIANS APP
