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 is

A parallel plate capacitor carries a harge Q. If a dielectric slab with dielectric constant K=2 is dipped between the plates, then

A parallel plate capacitor is to be designed with a voltage rating 1kV using a material of dielectric constant 10 and dielectric strength 10^(6)V/m .What minimum area of the plates is required to have a capacitance of 88.5pF ?

A parallel plate capacitor is charged to a certain voltage. Now if the dielectric material (with dielectric constant k ) is removed then the

A parallel plate capacitor is to be designed with a voltage rating 1 KV using a material of dielectrical constant 3 and dielectric strength about 10^(7) Vm^(-1) . [Dielectric strength is the maximum electric field a material can tolerate without break down, i.e, without starting to conduct electrically through partial 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 ?
