## Example Formula

The calculation of the capacitance of a cube is not as straightforward as that of a sphere or a parallel plate capacitor, mainly due to the complex electric field distribution. However, for a cube-shaped capacitor where each face is closely approximated by a plate of a parallel plate capacitor, a simplified formula can be used:

C = ε0A/d

Where:

1. C: is the Capacitance measured in Farads (F)
2. ε0: is the Permittivity of free space (~8.854 x 10-12 F/m)
3. A: is the Area of one face of the cube in square meters (m2)
4. d: is the Distance between the plates in meters (m), in this case, the length of an edge of the cube

Note: A = d d

## Who Wrote/Refined the Formula

The concept of capacitance and the associated formula were initially introduced by the British scientist Michael Faraday. The formula above is a simplified version of the more complex equation for capacitance. The model of a cube as a parallel plate capacitor is an approximation and does not account for edge effects and non-uniform field distribution.

## Real Life Application

In real life, the exact capacitance of a cube doesn't often come into play due to the complex field distribution. However, understanding the principles behind the calculation can aid in designing various electrical systems and circuits, such as in the optimization of space for integrated circuits in electronics.

## Key Individuals in the Discipline

Michael Faraday is a key individual in this field. His introduction of the concept of electric capacitance and his groundbreaking work in electromagnetism have significantly shaped the study of physics. Other scientists such as James Clerk Maxwell have also made substantial contributions, with Maxwell's equations being foundational to the field of electromagnetism.
