SUMMARY

The discussion centers on the application of the equation ∇·D = ρV to determine surface or linear charge density from an electric field D. It is confirmed that this equation can be utilized for charge distributions, provided that boundary conditions are properly integrated. Participants emphasize the importance of understanding the context and conditions under which this equation applies, suggesting further research for comprehensive insights.

PREREQUISITES
  • Understanding of Maxwell's equations, specifically the divergence operator.
  • Familiarity with electric displacement field (D) and its physical significance.

We know that ∇.D = ρV

My question is, if D is due to a linear or a surface charge distribution, can we apply this equation and get a surface or linear charge density?

Thank you very much

Yes, but I think, you have to sort of integrate within the boundary conditions. There is lot of information regarding this on google, if you do a search.
