Undergrad Determining continuity using Gauss' law

Click For Summary
SUMMARY

This discussion focuses on the application of Gauss' law to determine the continuity of electric fields in the presence of surface and volume charges. It establishes that for surface charges, the normal component of the electric field experiences a discontinuity proportional to the surface charge. Conversely, for non-singular volume charge distributions, there are no discontinuities in the electric field. The "Gauss pill-box argument" is highlighted as a method to prove these concepts using Gauss' law.

PREREQUISITES
  • Understanding of Gauss' law in electrostatics
  • Familiarity with electric field concepts and charge distributions
  • Knowledge of surface and volume charge characteristics
  • Basic principles of continuity in electric fields
NEXT STEPS
  • Study the "Gauss pill-box argument" for practical applications of Gauss' law
  • Explore the implications of surface charge density on electric field behavior
  • Investigate non-singular volume charge distributions and their effects on electric fields
  • Learn alternative methods for analyzing electric field continuity without Gauss' law
USEFUL FOR

Students of electromagnetism, physicists, and electrical engineers seeking to deepen their understanding of electric field behavior in relation to charge distributions.

I know how Gauss law helps us to calculate the discontinuity at a point on the surface of a surface charge.

Similarly using Gauss law, is there a way to determine the continuity at other points of electric field due to a surface charge or the continuity at all points of electric field due to a volume charge?

I don't understand the question. If there's a surface charge, the normal component of the electric field jumps by that surface charge (modulo some factors depending on the system of units). If you have a non-singular volume-charge distribution there are no discontinuities.

Can we prove it using Gauss law?
 
Sure, just use the "Gauss pill-box argument" to a situation where you have a non-singular charge distribution.

Thanks a lot... Anyway I have to clear some confusions regarding that. I will post my confusions tomorrow... I am so sleepy

Are there any other simple methods to prove it without using Gauss law?
 
In sci-fi when an author is talking about space travellers or describing the movement of galaxies they will say something like “movement in space only means anything in relation to another object”. Examples of this would be, a space ship moving away from earth at 100 km/s, or 2 galaxies moving towards each other at one light year per century. I think it would make it easier to describe movement in space if we had three axis that we all agree on and we used 0 km/s relative to the speed of...
