Course Description
First Half :
The first half of this course will run in online mode. It will consist of approximately 20 lectures and 5 tutorials. Online lectures will be uploaded each week. The weekly schedule will include one live Discussion Session (Friday, 11:00-11:50 hrs) to discuss any course related doubts, and one live Tutorial Session (Tuesday, 11:00-11:50 hrs) to learn problem-solving skills based on material covered in the previous few lectures. You will attend the Tutorial Session according to your respective Section. A Problem Set (assignment) will be given every week, and most problems will be worked out in the Tutorials. You are expected to attempt these problems before they are discussed in the tutorial. In addition, there will be a Discussion Forum where you can post any doubt/question which can be answered by anyone of you or the instructor.
Weekly Schedule (First Half) :
Lectures : Online (uploaded)
Discussion : Friday 11:00-11:50 (live online session)

Outcomes of this Course
This course is one of the three foundation Physics courses for the first year of Engineering and Sciences undergraduates and seeks to provide the students with the basics of the electromagnetic paradigm while strengthening the scientific foundations on which further study at IIT Kanpur is based. A thorough grounding in this course helps tackle many more courses across various disciplines in the undergraduate program involving applications of vector calculus and fields, flux, flow and potential in general.
