Transformers When secondary of a current transformer is open-circuited its iron core will be 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 hot because primary will carry heavy current cool as there is no secondary current ANSWER DOWNLOAD EXAMIANS APP
