C = 4πε₀r

Where:

C: is the Capacitance measured in Farads (F)
π: is the mathematical constant Pi
ε₀: is the Permittivity of free space (~8.854 x 10^-12 F/m)
r: is the Radius of the sphere in meters (m)

Who Wrote/Refined the Formula

Although it's difficult to attribute the formulation of the capacitance of a sphere to a specific individual, it is a result of the fundamental principles laid out in the broader discipline of electromagnetism. A key contributor to the field was James Clerk Maxwell, a Scottish scientist in the 19th century, whose formulation of Maxwell's equations forms the basis for modern electromagnetism.

Real Life Application

Understanding the capacitance of a sphere is critical in various fields, including electronics and power transmission. For instance, it's crucial in the design and manufacturing of spherical capacitors used in many electronic devices. Also, understanding capacitance is vital in power transmission lines where spherical conductors (though not perfectly spherical) are used, and knowledge of their potential to store and distribute charge is essential.

Key Individuals in the Discipline

James Clerk Maxwell, a key contributor to the field of electromagnetism, played a significant role in shaping our understanding of electric charge and capacitance. He formulated Maxwell's equations in the 19th century, providing a theoretical framework that still holds in modern physics. While he didn't specifically formulate the capacitance of a sphere, his contributions laid the groundwork for such calculations.
