Share Description
In this course, you will :
- Learn how to solve physics problems using tools like graphical analysis, algebra, vector analysis, and calculus.
- Charges, electric forces, electric field potential, magnetic fields, currents, magnetic moments, electromagnetic induction, and circuits are covered in the typical order of a first-semester university physics course.
- Each module includes reading links to a free textbook, complete video lectures, conceptual quizzes, and homework problems. The course concludes with an exam after the modules have been completed.
- This comprehensive course series is detailed and rigorous, similar to what is taught on campus.
