CoulombC
Source UnitThe coulomb (symbol: C) is the SI unit of electric charge, representing the quantity of electricity transported in one second by a constant current of one ampere. In terms of fundamental physical constants, one coulomb is equivalent to approximately 6.242 × 10^18 elementary charges, which is the charge of an electron. The coulomb is integral to the understanding of electromagnetic interactions, as it quantitatively describes the amount of electric charge in a system. This makes the coulomb pivotal in both theoretical and applied physics, particularly in contexts involving capacitors, electric fields, and electrochemical reactions. Additionally, the coulomb can also be expressed in terms of other base SI units, such as in the formula C = A·s, where A is amperes and s is seconds.
Current Use
Today, the coulomb is widely used in various fields, particularly in electrical engineering and physics. It is essential in calculations involving electric circuits, where current (in amperes) and voltage (in volts) interact to produce power, described as watts. In the automotive industry, the coulomb helps quantify the charge stored in batteries, which is crucial for the development of electric vehicles. Additionally, the coulomb is utilized in telecommunications for understanding signal transmission, where the flow of charge impacts the quality and speed of data transfer. Countries such as the United States, Japan, and members of the European Union employ the coulomb in both educational and professional settings, ensuring standardization in electrical measurements.

History & Origin
The coulomb is named after Charles-Augustin de Coulomb, a French physicist who is best known for his formulation of Coulomb's law in the 18th century. This law describes the electrostatic force between charged particles, laying the groundwork for electrostatics. The formal adoption of the unit occurred in the late 19th century as the field of electromagnetism developed. The International Electrotechnical Commission (IEC) officially adopted the coulomb as a standard unit in 1908, recognizing its importance in electrical engineering and physics. This historical context underscores the evolution of electrical measurement from qualitative observations to a standardized quantification of electric charge.
Etymology: The term 'coulomb' derives from the name of Charles-Augustin de Coulomb, reflecting his significant contributions to the study of electrostatics.
