A 4 μF capacitor is charged by a 200 V supply. It is then disconnected from the supply,
and is connected to another uncharged 2 μF capacitor. How much electrostatic energy of
the first capacitor is lost in the form of heat and electromagnetic radiation?

radar · Answer

I would think that the charge would simply be redistributed between the two capacitors.  Since their was no mention of any resistance there would be no energy loss (transfer) to heat.
