सवाल

Which syllabus does this course follow?

It follows the BTEUP (Board of Technical Education, Uttar Pradesh) syllabus of Power Electronics Lab (Semester 4). Where your polytechnic follows a different board or a revised syllabus, the centre follows your own syllabus.

Will it help in the semester examination?

Yes. Every unit is covered with solved examples, unit-wise MCQs and previous-year style questions for the BTEUP theory and practical exams.

Is the CRO used?

Yes. All waveforms are observed on a CRO / DSO and students learn to measure firing angle and voltage from the screen.
