Question

Two parallel plates, each having area A- 2737cm are connected to the terminals of a battery of voltage Vb 6 V as shown. The plates are separated by a distance d 0.38cm. You may assume (contrary to the drawing) that the separation between the plates is small compared to a linear dimension of the plate 1) What is C, the capacitance of this parallel plate capacitor? Submit 2) What is Q, the charge stored on the top plate of the this capacitor? Submit 3) A dielectric having dielectric constant K-4.3 is now inserted in between the plates of the capacitor as shown. The dielectric has area A 2737 cm and thickness equal to half of the separatio-0.19 cm) What is the charge on the top plate of this capacitor? d/2 Submit 4) What is U, the energy stored in this capacitor Submit 5) The battery is now disconnected from the capacitor and then the dielectric is withdrawn. What is V, the voltage across the capacitor? Submit
