Unit 3 - Electric Potential

Unit 3 is the biggest unit in the course, as it connects all your understanding of electric fields with a new concept of electric potential. Most FRQs on the AP exam will never solely ask about electric fields, but will almost always include electric potential as well because they are so intertwined. With electric potential also comes the idea of work and conservation of energy, ideas you have learned about in Mechanics. Finally, you'll learn some very important concepts about the electric fields and potentials inside conductors. Make sure you take your time going through this unit, as it is one of the most common topics on the AP exam.

Completing all lessons in this unit takes approximately 11.5 hours.
