Where Does the Energy Go in a Capacitor Without Resistance?

[Yegor]

The capacitor of capacitance C is charged by battery (emf = E) (assume that there is no resistance). In the end charge of the capacitor Q = C*E; Work done by the battery W = Q*E=C*E^2. But The energy of charged capacitor is U = (C*E^2)/2. Work doesn't equals to stored energy. Where we lost energy?? Can we forget about kinetic energy of the charges it this case?? Or it is exactly that "lost" energy?

It took some work with the PF search engine, but here's a long thread that should answer this question for you:

Thank you very much. As i understood, the model without resistance isn't really physical. With nonzero resistance everything is ok.
