28000 - General Physics T-2

Course Unit Page

Academic Year 2017/2018

Learning outcomes

Basic concepts of classical electromagnetism, with applications and exercises. Hits will be given to the limits of classical theory and the needs of a quantum theory to solve problems such as matter stability.


Course contents

Requirements/Prior knowledge. Attending and passing the final exam of a General Physics course (classical mechanics) are required in order to be able to attend with profit this course.
