Electrical field distribution in COMSOL?

09 November 2023 1 3K Report

Hi every one, in COMSOL multiphysics (v5.5), i want to simulate two parallel capacitor to know its electrical potential distribution and electric field but when i did that in electrical potential graph, we found a mistake that you can get a 0.5volt even when you are 10mm away from plates, i dont understand how it can be?

assume that you have battery is it possible to get 1volt from 1.5v battery even if you are 10mm away from it? firmly N0!

Simulation is done in 2D so that capacitor plates are assumed to be infinite in the surface normal (z) direction. Because of that, the result seems normal, but it can be verified by solving it as a boundary value problem, referring to Jackson Classical Electrodynamics chapter 2.
