A parallel plate capacitor, often known as two parallel conductive plates of finite size, has a homogeneous electric field between them.
The parallel plate capacitor is a device that uses two parallel plates connected across a battery to create an electric field between them.
The capacitance of a parallel plate capacitor is given by:
Where, is the permittivity of space , is the relative permittivity of dielectric material, is the separation between the plates and is the area of plates.
