A parallel-plate capacitor has an effecting plate area of 100cm2(each plate) separated by a dielectric 0.5mm thick. Its capacitance is 442µµF and it is raised to a potential differences of 10kV. Calculate from first principles (a) potential gradient in the dielectric (b) electric flux density in the dielectric . (c) the relative permittivity of the dielectric material.
