सवाल

Will I learn to use a CRO?

Yes. Reading amplitude, time period and frequency on a CRO / DSO is practised with examples.

Are range extension numericals included?

Yes. Shunt, multiplier, energy meter and bridge problems are solved.

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.
