Question

A parallel plate capacitor is fully charged by connecting it to a battery. While the battery is still connected to the capacitor, the distance between the plates of the capacitoris halved, the energy densityof the capacitor

Answer #1

the separation between the plates is halved in such a way that so
charge leaks off As the plate separation is being halved which of
the following parameters remains constant?

A Parallel plate capacitor is charged fully using a 48 V battery
such that the charge on it is 230 pC and the plate separation is 3
mm. The capacitor is then disconnected from the battery and the
plate separation doubled. What is:

increased
The new potential difference between the plates
The Field between the plates after increasing the separation
How much work does one have to...

A parallel plate capacitor, in which the space between the
plates is filled with a dielectric material with dielectric
constant κ = 9.8, has a capacitance of C=472 μF and it is connected
to a battery whose voltage is V=30 V and fully charged. Once fully
charged, while still connected to the battery, dielectric material
is removed from the capacitor.
How much change occurs in the energy of the capacitor; final
energy minus initial energy?
