WebSep 12, 2024 · We begin with the differential form of Gauss’ Law (Section 5.7): ∇ ⋅ D = ρ v Using the relationship D = ϵ E (and keeping in mind our standard assumptions about material properties, summarized in Section 2.8) we obtain ∇ ⋅ E = ρ v ϵ Next, we apply the relationship (Section 5.14): E = − ∇ V yielding ∇ ⋅ ∇ V = − ρ v ϵ WebSep 12, 2024 · For surface S2 the equation becomes ∮C→B ⋅ d→s = μ0 d dt[ϵ0∬SurfaceS2→E ⋅ d→A]. Gauss’s law for electric charge requires a closed surface and cannot ordinarily be applied to a surface like S1 alone or S2 alone. But the two surfaces S1 and S2 form a closed surface in Figure 16.2.2 and can be used in Gauss’s law.
