What is NPTEL?

The National Programme on Technology Enhanced Learning (NPTEL) was initiated by seven Indian Institutes of Technology (Bombay, Delhi, Kanpur, Kharagpur, Madras, Guwahati and Roorkee) also the Indian Institute of Science, Bangalore in 2003 NPTEL NCER Assignment 6 answers. It consists of Five core disciplines were identified, namely, civil engineering, computer science and engineering, electrical engineering, electronics and communication engineering and mechanical engineering and 235 courses in web/video format were developed in this phase.

The main goal of NPTEL Phase II (2009-14) was to build on the engineering and core science courses launched previously in NPTEL Phase I. so 600 web and video courses were created in all major branches of engineering, physical sciences at the undergraduate and postgraduate levels and management courses at the postgraduate level. Several improvements such as indexing of all video and web courses and keyword search were implemented.

What is NCER NPTEL?

This course looks at the operating principle of a range of non-conventional energy resources, materials used, characterization, and key performance characteristics. The technologies looked at will include, Solar energy, Wind, Batteries, Fuel cells, and Geothermal conversion. The advantages and limitations of these technologies in comparison to conventional sources of energy will also be examined.

What is the NPTEL Assignment?

Nptel mainly consists of 12-week courses. Every week NPTEL provides video lectures as well as different study materials. Every week one quiz is provided. Each quiz has a specific time deadline. After the end of time, deadline NPTEL provides a solution of that quiz as well as provides marks obtained by the registered candidate. Out of 12 assignments, only the top 8 assignment marks are considered. Weightage of assignment marks is 40 %.
