Uniform charge distribution in a conductor

Click For Summary

Discussion Overview

The discussion centers around the uniform charge distribution in conductors, exploring how and why charge can be evenly distributed, the conditions required for such distribution, and the implications of electrostatic equilibrium. Participants also consider the factors influencing charge distribution and the practical occurrence of these phenomena.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Saad questions how charge can be uniformly distributed in a conductor and whether external influences or tools are necessary for this configuration.
  • One participant asserts that inside a conductor, the only stationary charge distribution is uniform and equal to zero, as any net charge would create an electric field and change the distribution.
  • Several participants note that the shape of the conductor influences charge distribution.
  • Another participant clarifies that the charge in question is not within the conductor but rather on its surface.
  • A later reply states that in near-perfect conductors, achieving a uniform volume charge distribution is impossible and suggests considering such bodies as perfect dielectrics charged by unknown means.

Areas of Agreement / Disagreement

Participants express differing views on the nature of charge distribution in conductors, particularly regarding the role of shape and the distinction between surface and volume charge. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are limitations regarding assumptions about charge distribution, the definitions of conductors and dielectrics, and the implications of electrostatic equilibrium that are not fully explored in the discussion.

TL;DR
Uniform distribution of charge in a conductor
How and why can charge be evenly or uniformly distributed in a conductor? How can such near perfect configuration of charge be achieved? Is outside influence (or force) or any special scientific tools or instruments required to accomplish that? By definition, electrostatic equilibrium is simply a state of the absence of net motion of charge in a conductor so electrostatic equilibrium, by itself, does not appear to have a bearing on charge distribution? What are some factors influencing this? Could someone please shed some light on this and how often this occurs in reality?

Thanks,
Saad

Inside a conductor the only possible stationary charge distribution is uniform … and equal to zero. Any accumulated net charge will lead to a non-zero electric field and therefore a changing charge distribution.

That's not charge in the conductor though. It is charge accumulated on the conductor's surface.

In (near) perfect conductors it's impossible to achieve a uniform volume charge distribution. Problems with such configurations are offered to you as a student to study basic electromagneric laws. If you like, you can think of these bodies as of perfect dielectrics uniformly charged by some (unknown) means.
