A certain substance consists of a dielectric constant of 2.8 and a dielectric strength of around 14 MV/m. When it is employed as the dielectric material in a parallel-plate capacitor, determine what minimum area must the plates of the capacitor encompass to get a capacitance of 8.1 x 10-2 µ F and to make sure that the capacitor will be capable to endure a potential difference of around 3.6 kV?
