Two parallel plates, each having area A = 2797cm2 areconnected to the terminals of a battery of voltage Vb = 6 V asshown. The plates are separated by a distance d = 0.53cm. You mayassume (contrary to the drawing) that the separation between theplates is small compared to a linear dimension of the plate.
1) What is C, the capacitance of thisparallel plate capacitor?
What is Q, the charge stored on the top plate of thethis capacitor?.
A dielectric having dielectric constant ? = 4.5 is nowinserted in between the plates of the capacitor as shown. Thedielectric has area A = 2797 cm2 and thickness equal to half of theseparation (= 0.265 cm) . What is the charge on the top plate ofthis capacitor?
What is U, the energy stored in thiscapacitor?

The battery is now disconnected from the capacitor andthen the dielectric is withdrawn. What is V, the voltage across thecapacitor?

A parallel plate capacitor is connected across a 25-V battery. If,with the battery still connected, you pull the plates apart untiltheir separation is now twice what it originally was,thecapacitance of these plates, the energy stored in the capacitor,and the excess charge on each plate are now all one half of whatthey originally were.
