Hello,
I am currently reading about the topic mentioned in the title of this thread. For the most part, I understand the derivation; however, at the end of the derivation, the author adds one little condition:
"Where is the energy in a parallel plate capacitor actually stored? Well, if we think about it, the only place it could be stored is in the electric field generated between the plates."
How is the energy not stored in the capacitors? Can't the charges, that comprise the charge of the plates of parallel capacitor, possesses the potential energy? I mean, after all, they the ones having a force applied over them through a distance (the distance between how far apart the parallel plates are)? I know the idea is useful, for it allows us to define the energy density of an electric field. Why and how is it stored in the electric field between the plates?
