A parallel plate capacitor filled with air carries a charge Q. The battery is disconnected, and a slab of material with dielectric constant, is inserted between the plates. What is the potential difference across the plates after inserting the slab in terms of the potential of the battery?

An air-filled parallel-plate capacitor with capacitance C0 stores charge Q on plates separated by distance d. The potential difference across the plates is ΔV0 and the energy stored is PEC,0. If the capacitor is disconnected from its voltage source and the space between the plates is then filled with a dielectric of constant κ = 2.00, evaluate the ratios (a) Cnew/C0, (b) ΔVnew/ΔV0, and (c) PEC,new/PEC,0.

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The battery is now disconnected from the capacitor andthen the dielectric is withdrawn.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?
