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 none of above will happen hot because of heavy iron losses taking place in it due to high flux density cool as there is no secondary current hot because primary will carry heavy current none of above will happen hot because of heavy iron losses taking place in it due to high flux density ANSWER DOWNLOAD EXAMIANS APP
