सवाल

Which syllabus is followed?

The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Special Electrical Machines (Electrical Engineering, Semester 5). If your university or college follows a different syllabus, the centre teaches from your own university syllabus.

Is this a compulsory subject?

No. In the AKTU scheme it is offered as a Departmental Elective-I option in Semester 5 of Electrical Engineering; it is taught for students who have chosen this elective.

How is the subject examined?

AKTU assesses it through sessional tests, assignments and attendance, and an end-semester university examination; the centre covers every unit with theory, derivations and numericals.

Are previous-year questions practised?

Yes. Unit-wise AKTU previous-year questions, short-answer questions and the test series are solved in class.
