A parallel plate capacitor is made from two plates 7 cm^2 in area, with a plate separation of 3 mm. The capacitor is fully charged across a 30 V battery, and then disconnected.

How much charge is on the capacitor?

Now material with a dielectric constant of 30 is inserted to fill the space between the plates, (with the battery disconnected), What is the charge on the capacitor?

What is the energy stored in the capacitor?

What the field between the plates?

What the potential difference across the capacitor?

How much work do you have to do to insert the dielectric in between the plates?

A parallel-plate capacitor is constructed of plates with area 2.5 m2 that are separated by 0.5 mm of air (dielectric constant Ka = 1:0006). The capacitor is connected to a 9 V battery and fully charged. The battery is then disconnected, and quartz is inserted to ll the gap between the plates (dielectric constant Kq = 4:3). Determine whether the energy density of this capacitor increased or decreased when the quartz was inserted, and by how much.
