When C decreases from 10 uF to 1 uF voltage increases from 10 V to 100 V
So energy E=C*U^2/2 changes from 1e-5*10*10/2=0.5e-3 J to 1e-6*100*100/2=
0.5e-2 J. Where did extra energy come from? To drain oil one SHOULD work!
Oil is ATRACTED to space betwin plates by electric field! Do drain it
extra energy is needed. For example the energy of gravity... So this is
a machine converted mecanical energy to electrical energy. It is known
some devises worked in such a way (Von de Graaf geneator, there is some
analogy)...
Also it is known electrostatic pump, worked in oposite way...
It is very similar to oil drained from capasitor, but there oil is
atracted TO space betwin plates and electric energy is converted to
mecanical one...
Good oldfashoned phisics. I like it...
