TRAINING ON LED BULB ASSEMBLING

Department of Physics

Vocational Education Training

Objective

Objective of the LED bulb assembling training programme is to provide an opportunity for the students of various faculties to develop an occupational life skill.


Outcome

By this course students gain basic electronics and theory of electronic components and its applications. After the completion of the course students would be able to assemble LED bulbs.


Beneficiaries

Interested students from various faculties may be admitted to the programme limiting the maximum number to 25 in each batch.


Resource Person:

Dr Roy Sebastian K
Associate Professor
