The diameter of each plate of an air capacitor is `4cm`. To make the capacity of this plate capacitor equal to that of a sphere of diameter `20`cm, the distance between the plates is`x times10^(-3)`m .Then `x` is,,.

The capacitance of a parallel plate capacitor formed by the circular plates of diameter 4.0 cm is equal to the capacitance or a sphere of diameter 200 cm. Find the distance between two plates.

The diameter of each of plate of a parallel plate air capacitor is 0.06 m. What should be the distance between its plates, so that its capacitance becomes equal to that of a sphere of diameter 0.1 m?

What will be the effect on the capacity of a parallel plate capacitor when the area of each plate is doubled and the distance between them is also doubled?

What is the area of the plates of a parallel plate capacitor of capacity 2pF with separation between the plates 0.5 cm?

The capacity of a parallel plate capacitor is 10 μF when the distance between its plates is 9 cm. What will be its capacity if the distance between the plates is reduced by 6 cm.

Between the plates of a parallel plate capacitor of capacity C, two parallel plates, of the same material and area same as the plate of the original capacitor, are placed. If the thickness of these plates is equal to 1/5 th of the distance between the plates of the original capacitor, then the capacity of the new capacitor is

A parallel plate capacitor with air between the plates has a capacitance 2muF . The capacity of the condenser when the distance between the plates is reduced to half of initial distance is
