Capacitance is a fundamental property in physics and electronics that describes the ability of a system to store an electric charge. The study of capacitance of parallel cylindrical surfaces falls under electrostatics and electronics engineering. This tutorial covers the formulas for calculating this capacitance, who developed the formulas, their real-life applications, important individuals related to this topic, and some fascinating facts about it.

Capacitance of Parallel Cylinders = CV^{-1} |

The capacitance (C) of two parallel cylindrical surfaces can be calculated using the following formula:

C = 2πε_{0}l / ln(b/a)

Where:

- C: is the Capacitance, measured in Farads (F)
- ε
_{0}: is the Permittivity of free space (~8.854 x 10^{-12}F/m) - l: is the length of the cylinders, in meters (m)
- b: is the distance to the outer cylinder, in meters (m)
- a: is the distance to the inner cylinder, in meters (m)
- ln: denotes the natural logarithm

The concept of capacitance was first introduced by Michael Faraday. The formula for the capacitance of parallel cylindrical surfaces is an important part of electrostatics and electronics engineering, and its derivations can be found in many standard textbooks on these topics.

The formula for capacitance of parallel cylindrical surfaces finds application in the design and operation of coaxial cables, used extensively in telecommunications and internet networks. Understanding this principle is crucial for maintaining the efficiency and effectiveness of data transmission in these cables.

Michael Faraday is a pivotal figure in this discipline, having introduced the concept of electric capacitance. Moreover, James Clerk Maxwell's work, which consolidated electricity and magnetism into a unified theory, played a key role in understanding and applying capacitance.
