hi guys
This query comes about after the comment by BillyT
https://www.physicsforums.com/threads/energy-in-a-capacitor.840145/page-2
is what he is saying correct, or only for the very specific situation he is involved with
and it doesn't apply to every day capacitors ?
everywhere I read tells me that the energy is stored in the electric field
eg ...
http://hyperphysics.phy-astr.gsu.edu/hbase/electric/capchg.html
meaning that the dielectric ... plastic, paper, air, vacuum etc etc just happens to be within the electric field
The electric field is permeating the dielectric but it is where the energy is stored, rather than specifically in the dielectric ?
just trying to clarify my understanding
cheers
Dave

in post#22 in this threadPS if you are working with large high-voltage capacitors, as I have in a controlled fusion project, the stress in the dielectric, which is where the energy is stored, like in a spring, will not be completely releaxed by briefly shorting the poles together. - It will relax in the next few minutes, recharging the capacitor - making it quite dangerous again. Leave the terminals connected for several minutes to fully discharge capacitor.

Charging the capacitor stores energy in the electric field between the capacitor plates
