The plates of a parallel plate capacitor have area of `90cm^2` each and are separated by 2.5mm. What would be its capacitance?`[epslion_0 =8.85 * 10^(-12) C^2N^(-1) m^(-2)]`

The plates of a parallel plate capacitor have an area (20 cm^2) each are separated by a distance of 2.5 mm. The capacitor is charged by connecting it to a 400V supply. How much electrostatic energy is stored in the capacitor?

What is the area of the plates of a 0.1 µF parallel plate air capacitor, given that the separation between the plates is 0.1 mm.

For a parallel plate capacitor with each plate of area "A. separated by distance .d. in air, its capacitance is given by C= epslion_0 A/d : Represent the charge .q. given to a capacitor of capacitance C with potential difference .V. in a graph. What will be the shape of the curve ?
