Well, Eric Weisstein say an electron has a mass ofDoes a fully charged cap, wiegh more than an uncharged cap?
Does a charged battery wiegh more?

Of course, as always, jmshio
a charged capacitor weighs exactly the same as an uncharged capacitor, because the electrons have simply switched sides, but the total is unchanged.
An electrical charge does not have weight. Charge is a property that is possessed by an electron, and the electron itself has weight. The question is the same as asking if age has weight. OK, I am a person, and one property, or characteristic, that I possess is that I have weight. As I age, my weight may change. But that is not because age itself has weight, and the change in age has caused the change in weight. In the same sense, charge does not have weight.
This whole topic is about things on the atomic level. The change in mass may not have anything to do with the change in particle count. What is going on at the atomic level is the real effect.From non-relativistic physics, a charged capacitor weighs exactly the same as an uncharged capacitor, because the electrons have simply switched sides, but the total is unchanged.
There are those that purport that an increase in energy state will result in an increase in mass due to relativity, but the effects are so astronomically negligible, even on an atomic level, that this is a bit asinine. It is typically presented by those that want to show off their alleged knowledge, not for real effect.
