An air -filled parallel-plate capacitor is to be constructed which can store`12 mu C` of charge when operated at `1200V.`What can be the minimum plate area of the capacitor?The dielectric strength air is `3xx10^6Vm^(-1).`

A parallel plate capacitor is to be constructed which can store q = 10 muC charge at V = 1000 volt. The minimum plate area of the capacitor is required to be A_(1) when space between the plates has air. If a dielectric of constant K = 3 is used between the plates, the minimum plate area required to make such a capacitor is A_(2) . The breakdown field for the dielectric is 8 times that of air. Find (A_(1))/(A_(2))
