सवाल
Which syllabus is followed?
The NCVT / DGT CTS Workshop Calculation & Science Year 2 syllabus for electrical group trades. Where your ITI (SCVT) syllabus differs, the centre follows your own syllabus.
Is trigonometry difficult?
It is taught with simple trade examples such as ladders, poles and cable lengths, and plenty of practice.
Are AC circuit numericals included?
Yes. Impedance, power factor and three-phase power problems are practised for the CBT exam.
