Questions

Is this course for both Electrical and Electronics branches?

Yes. It is taught in Semester 3 of both branches as per the BTEUP scheme.

Will I see circuits working?

Circuits are explained with simulations and lab demonstrations where available.

Is this course based on the BTEUP syllabus?

Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
