A ceramic capacitor is to be made so that it has a capacitance of 100 pF and is to be operated from a 750 V supply. Allowing for a safety factor, the dielectric has a strength of 500 kV/m. Determine
(a) the thickness of the ceramic,
(b) the plate area if the relative permittivity of the ceramic is 3.2,
(c) the charge and energy stored when the capacitor is connected to its rated supply voltage, and
(d) the flux density under these conditions.
