Capacitor exceeds the dielectricstrength of the dielectric

Reference no: EM13654106

If the electric field inside a capacitor exceeds the dielectricstrength of the dielectric between its plates, the dielectric will break down, discharging and ruining the capacitor. Thus, the dielectric strength is the maximum magnitude that the electricfield can have without break-down occurring. The dielectricstrength of air is 3.0 x 10⁶ V/m, and that of neoprenerubber is 1.2 x 10⁷ V/m. A certain air-gap,parallel-plate capacitor can store no more than 0.085 J ofelectrical energy before breaking down. How much energy can this capacitor store without breaking down after the gap between itsplates is filled with neoprene rubber? Take the dielectric constant of air to be 1.00054, and of neoprene rubber to be 6.7.
