When a thick plate of a dielectric is place in the air space of a parallel plate capacitor, then

The capacitance of a parallel plate capacitor increases with

Why is a parallel plate capacitor named so?

Derive an expression for capacitance of a parallel plate capacitor.

A slab of a material of dielectric constant K has the same area as the plates of a parallel plate capacitor, but has a thickness 3/4 d , where d is the separation between the plate. How is the capacitance changed when the slath is inserted between the plates.

Explain Polarisation of dielectric slab. What is the effect on capacitance if we introduce a dielectric slab of dielectric Constant K in between parallel plate capacitor, thickness of slab is less than the separation between the plates.
