Sunantoro,
When people discuss about capacitor, they use "Charge" and "Energy"
interchangeably. This is rather confusing or ambiguous (to me).
Can we simply change it with "Electrons" which flow and accumulate in one
plate when the opposite plate becomes lack of it (electrons)?
Don't think any electrons accumulate on the plates. Where would they stay.
I'm thinking now that charge is the wrong term to use for the resulting
stored energy. We often say that a capacitor stores a charge, and it
certainly has to be charged, and the text books talk coulombs something
fierce when they get to capacitors. I still can't see the energy in a cap
as stored electrons, that's particles. And fields are not supposed to be
particles, or am I wrong there too.
By using this understanding, I believe there is no need to elaborate further
on "Charge" or "Energy",
Actually, I have a problem with the term energy to describe what is stored
too since energy includes time, i.e. watt seconds, joules. But the stored
energy is at rest. OR are we talking about the amount of joules it took
to charge... oops, to store the energy.
