Discussion Overview
The discussion revolves around calculating the maximum electric field (Emax) in concentric cylinders, specifically addressing how the formula might change when additional inner cylindrical electrodes are introduced. The context appears to be technical, with implications for modeling and simulation in electrical engineering or physics.
Discussion Character
- Technical explanation, Exploratory, Debate/contested
Main Points Raised
- One participant presents the formula for Emax as Emax = V/a ln(b/a) and questions how this formula would adapt for three inner cylindrical electrodes.
- Another participant suggests that the problem becomes more complex with additional electrodes and inquires about the level of precision required for the solution.
- There is a mention of using simulation software, specifically COMSOL, to potentially address the complexity of the problem.
- A participant indicates they have access to FEMM 4.2 software, which may be relevant for modeling the electric field.
- There is a question about the educational context of the inquiry and whether the original poster has access to electric field modeling software through university resources.
Areas of Agreement / Disagreement
Participants do not reach a consensus on how the formula changes with additional electrodes, and the discussion remains unresolved regarding the specifics of modeling the scenario.
Contextual Notes
The discussion highlights the complexity introduced by additional electrodes and the potential need for simulation tools, but does not resolve the mathematical or theoretical implications of these changes.

That would look to be a much more complicated problem than just concentric cylinders. How exact of a solution do you need? Do you have access to simulation software like COMSOL?

Thanks for the reply
I only have FEMM 4.2 software.

Are you in university? What is the context of this question? Do you know anybody with access to electric field modeling software?donkitano123 said:Thanks for the reply
