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.

History & Origin
The concept of electric charge dates back to ancient Greece, where philosophers like Thales of Miletus observed static electricity by rubbing amber with fur. However, the elementary charge as a quantized unit emerged in the early 20th century. Its formal definition was significantly influenced by the work of Robert Millikan, who conducted the oil drop experiment in 1909, measuring the charge of an electron and establishing that electric charge occurs in discrete amounts. This pivotal experiment provided evidence for the quantization of charge, leading to the recognition of the elementary charge as a fundamental constant in physics.
