Parallel Plate Capacitor
CHAPTER 44.1 Parallel Plate Capacitor
A parallel plate capacitor is formed by two plates separated by a distance d. If A is the area between the two plates the capacitance between the two plates is given by
where,
d = separation between the plates
A = Area of each plate
= permittivity of free space or 0.225 pF /inch
= relative permittivity of the medium between the plates

There are therefore three factors upon which the capacitance of a parallel plate capacitor depends – the area of the overlap, the separation between the plates and the dielectric constant of the material between the plates.
