The topic of the video, "Electric potential: Example 2.7," covers the concept of electric potential and its application to a specific example problem. In electrodynamics, electric potential is a fundamental concept that helps understand the behavior of electric charges in an electric field. In this video, we explore the concept of electric potential and its relationship with electric fields. We solve Example 2.7 from David J. Griffiths' book, which involves finding the electric potential at a point due to two point charges. This example illustrates how to apply the concept of electric potential to solve real-world problems in electrodynamics.
