keeps constant the potential difference V = 100 V, as shown in Figure 2.A dielectric slab, with relative permittivity Er .= 15 is inserted in C1, filling completely the air gap Calculate the charge accumulated by the described arrangement of capacitors before and after the insertion of the dielectric slab.(a)[6] (b)Calculated the change in the charge accumulated by C2.[2] (c)Calculate the potential difference between the plates of Cı before and after the insertion of the dielectric slab. (d)Calculate the energy stored in the described arrangement of capacitors[6]before and after the dielectric slab insertion. (e)Calculate the energy provided by the power supply (the DC source V) [5]
