Creative works of 19208,18208,17208 DECE students

Click here for ECPS(EC-105)lectures

These creative works are drawn/written by DECE students of Government polytechnic amadalavalasa. One topic of Electronic Devices and power supplies(EC-105) is assigned to each student, and the students are asked to relate the concept of this topic to any thing around you. The motto behind asking the students to link the subject to the things around them is 

1)To create the interest in the students about the subject, which will give them chance to remember the basic concepts even after years. This will be useful in the present competitive world to remember the concepts until the objective exams and to perform well in interviews
2) To create an awareness about thinking social problems surrounding them
