Transformers When secondary of a current transformer is open-circuited its iron core will be hot because primary will carry heavy current cool as there is no secondary current hot because of heavy iron losses taking place in it due to high flux density none of above will happen hot because primary will carry heavy current cool as there is no secondary current hot because of heavy iron losses taking place in it due to high flux density none of above will happen 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 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 ANSWER DOWNLOAD EXAMIANS APP
