Electronics Mechanic NSQF-4 First Year Book

In the first year of ITI Electrician training, trainees will gain essential knowledge of safety practices, environmental awareness, and trade tools. They will explore the fundamentals of electricity, electronic components, circuit testing, soldering techniques, and power supply construction. Practical skills include handling batteries, testing digital and linear ICs, using simulation software, and working with both through-hole and SMD components. By the end of the first year, trainees will be skilled in assembling, testing, and troubleshooting various electrical and electronic circuits.
