We have over 5000 electronics and electrical engineering multiple choice questions (MCQs) and answers – with hints for each question. When a load is connected to a transformer current (say I 2 ) flows through secondary coil thus an M.M.F (N 2 I 2 ) is produced, this produces the secondary flux. A current flowing in the primary coil generates a time-varying magnetic field in the core. When AC supply is given to the transformer, the flux will depend on. h�bbd``b`NA@�����$�5��L �{ ��� �0��qu��$�6W !�$�w ��@B��~�����d�p �3^�` p�� What is the operating principle of a Transformer?
