Questions
Which syllabus is followed?
The NCVT / DGT CTS Electrician Year 2 trade theory syllabus. Where your ITI (SCVT) syllabus differs, the centre follows your own syllabus.
Are machine numericals covered?
Yes. Back EMF, turns ratio, synchronous speed, slip and efficiency problems are practised.
Will this help in apprenticeship or jobs?
Yes. Motors, transformers and control panels are the core of maintenance electrician jobs in industry.
