If it is an approximation does anyone know the more accurate formula

Yes, it is an accurate formula. Why do you doubt it?

I just thought that effects at the edge of the plate would affect it slightly

Its called fringe effect in capacitor.

A parallel plate capacitor is a simple electrical device that consists of two parallel conductive plates separated by a small distance, often filled with a dielectric material. It is used to store electrical energy by creating an electric field between the plates.

A parallel plate capacitor works by storing electric charge on its two plates, which creates an electric field between them. This electric field stores energy in the form of potential energy, which can be released when the capacitor is discharged.

The capacitance of a parallel plate capacitor is affected by several factors, including the distance between the plates, the area of the plates, and the type of dielectric material between the plates. The capacitance is directly proportional to the area of the plates and inversely proportional to the distance between them.

The capacitance of a parallel plate capacitor can be calculated using the formula C = ε₀A/d, where C is the capacitance, ε₀ is the permittivity of free space, A is the area of the plates, and d is the distance between the plates. The unit of capacitance is Farads (F).

Parallel plate capacitors have many practical applications, including as energy storage devices in electronic circuits, in power factor correction, and in filters and tuning circuits in radios and televisions. They are also commonly used in sensors, such as accelerometers and pressure sensors.
