A parallel plate capacitor is to be desigined with a voltage rating 1kV, using a material of dielectric constant 3 and dielectric strength about `10^7 Vm^(-1)` (Dielectric strength is the maximum electric field a material can tolerate without breakdown, i.e., without starting to conduct electricity through partical ionisation. ) For safety, we should like the field never to exceed, say `10%` of the dielectric strength. What minimum area of the plates is required to have a capacitance of 50 pF?

Explanation

`19 cm^(2)`
