1.

A parallel plate capacitor is to be designed, using a dielectric of dielectric constant 5, so as to have a dielectric strength of `10^(9)V*m^(-1)`. If the voltage rating of the capacitor is 12kV, the minimum area of each plate required to have a capacitance of 80pF isA. `10.5xx10^(-6)m^2`B. `21.7xx10^(-6)m^2`C. `25.0xx10^(-5)m^2`D. `12.5xx10^(-5)m^2`
