and becomes fully charged the capacitor is then disconnected and
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?**

**An air filled k=1 ideal parallel plate capacitor has a
capacitance of C. If the area of the plates is doubled insert a
dielectric material k=2 and the distance between the plates is
halved what is the new capacitance?**

**The area of a parallel plate capacitor is being
increased while it is connected to a battery During this process
the amount of charge on the plates.**

**A parallel plate capacitor is connected to a 3V battery
and becomes fully charged. The capacitor is then disconnected, and
the separation between the plates is doubled in such a way that no
charge leaks off. As the plate separation is being doubled, what is
the potential difference across the capacitor**
