Question

F o x f capacitor is charged by a 200 volt supply it is then disconnected from the supply and is connected to another uncharged to f capacitor how much electrostatic force of the first capacitor is dissipated in the form of heat and electromagnetic radiation

Answer 1

The energy stored on a capacitor can be calculated from the equivalent expressions: This energy is stored in the electric field. and will have stored energy E = x10^ J. From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV.
