सवाल

Which syllabus is followed?

The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Electric Drives (Electrical Engineering, Semester 6). 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-III option in Semester 6 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.
