Instructor: Sameen Maruf

GSN-1153: APPLIED PHYSICS

Credit Hours: Three

Pre-requisites: Basic Calculus and Physics

Course DescriptionAn introductory course in physics required

for Electrical Engineers. In the first part of this course, we will only consider static charges. Static electric charges generate electric fields. Next, we will consider moving electric charges or steady charged currents; these generate a magnetic field. Thus the students will learn the basics of electricity and magnetism.

Expected OutcomesBy the end of the course, students will be

able to:Define and analyze the concepts of electric

charge, current and magnetism.Discuss the laws of electricity (e.g.

Coulomb’s and Ohm’s Law) and magnetism.

Solve a variety of problems of basic electricity.

Required TextbookPrinciples of Physics by David Halliday,
