Transformers In a transformer, leakage flux Is minimised by interleaving the primary and secondary windings Helps in transfer of energy Produces mutually induced emf Is negligible at full load Is minimised by interleaving the primary and secondary windings Helps in transfer of energy Produces mutually induced emf Is negligible at full load ANSWER DOWNLOAD EXAMIANS APP
Transformers When secondary of a current transformer is open-circuited its iron core will be cool as there is no secondary current hot because primary will carry heavy current hot because of heavy iron losses taking place in it due to high flux density none of above will happen cool as there is no secondary current hot because primary will carry heavy 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
