SUMMARY
The discussion centers on the concept of surface charge in the context of a uniformly charged solid sphere, as presented in Griffiths' "Introduction to Electrodynamics." Participants clarify that a uniformly charged sphere does not have a surface charge in the same way a conducting sphere does. The key distinction is that surface charge refers to a finite amount of charge on an infinitely thin layer, while a uniformly charged sphere has a consistent charge density throughout its volume. This leads to the conclusion that the electric field remains continuous at the surface of a uniformly charged solid sphere, contrasting with the discontinuity observed in the presence of a surface charge.
