Howdy All,

    Imagine an air variable capacitor with plates fully engaged and the
capacitor fully charged.

    Let's use the example of .001µF charged to 10,000 volts. Stored energy =
joules = .5CV^2 = .05 watt=seconds.

    What happens to the energy of the fully charged capacitor when the
plates are rotated to the 0µF capacitance position?
1) There is no such thing as 0 capacitance between two charged objects.
2) The potential difference between the two objects increases as the plates
are separated.

Therefore, nothing is lost. .5 C1V1^2=.5 C2V2^2
