A parallel plate capacitor of area 1.4 cm² is filled with three dielectrics with constants K1=2.5, K2=1.3 and K3=6.5. The dielectrics are placed as shown in the figure, each occupyinq half the total area, while the volume of the first double of the other two. If the separation distance between the plates is 4 mm What is the capacitance before including the dielectrics? What is the capacitance after including the dielectrics? If we connect the capacitor to a battery of 12 V, What is the energy stored?
