2) A 8 volt battery is connected to a parallel plate capacitor with an initial capacitance of 7 micro-farads without a dielectric. While still connected to the battery, the sheets are moved a factor of 8 times further apart and a dielectric with a dielectric constant of 1.7 is inserted between the sheets. Then, the battery is disconnected, and after the battery is disconnected, the dielectric is removed and the sheets are brought a factor of 2 times closer together....

A capacitor is connected to a 7 volt battery which is initially does not have a dielectric. The battery is disconnected, the plates are moved further apart by a factor of 3, and a dielectric of 1.9 is inserted between its plates. The stored energy in this configuration is 400 micro-joules. What was the original value of the capacitance (of the capacitor) in micro-farads? That is, the capacitance when connected to the battery without a dielectric.

A capacitor has a capacitance of 49 micro-farads without a dielectric while connected to a 20 volt battery. Then the distance between the plates is decreased by a factor of 5 and a dielectric with a dielectric constant of 2.29 is inserted between the plates of the capacitor while still connected to the same battery. What is voltage, in volts, across the capacitor after the dielectric and the distance between the plates have been changed?

A 193 volt battery is connected to a 0.3 microfarad parallel-plate capacitor with air between the plates. Now the battery is disconnected, with care taken not to discharge the capacitor. Some paper is then inserted between the plates completely filling up the space. What is the final potential difference between the plates ? (the dielectric constant for air is = 1 and for the paper inserted is = 3)
