Calculating Potential of a Charged Plate: Figuring Out Fig. 23-1

Click For Summary

Discussion Overview

The discussion revolves around calculating the electric potential of charged plates, specifically referencing a figure (Fig. 23-1) that illustrates the concept. Participants explore methods for determining potential differences between plates, touching on theoretical and mathematical aspects.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants explain that voltage is defined as a path integral of the electric field between two points, emphasizing the path independence of voltage.
  • Others suggest using Gauss's Law to determine the electric field between the plates and propose integrating this field over the distance between the plates, noting the assumption of a constant electric field.
  • One participant requests the specific figure (Fig. 23-1) for clarity, indicating that the lack of visual data complicates the discussion.

Areas of Agreement / Disagreement

Participants present multiple approaches to calculating potential, but there is no consensus on a single method or the specifics of the figure referenced. The discussion remains unresolved regarding the exact calculation process.

Contextual Notes

There are limitations due to the absence of the referenced figure and potential assumptions about the configuration of the plates that have not been explicitly stated.

I saw this statement in a book. May I know how to calculate the potential of a charged plate?

As always, the voltage between A and B is defined as a path integral of the electric field starting at point A and ending at point B. Of course, since the voltage is path independent you may integrate E over a straight line without loss of generality.

Use Gauss's Law to determin the electric field. Then integrate this electric field over the distance between the two plates; This is not that difficult since the E-field is constant; i AM ASSUMING TWO PLATES HERE
 
Could you present us with that "Fig. 23-1".It's kinda difficult to speculate,when we lack the data ...:-p


Daniel.

P.S.Well,at least for me it is...
