Coulomb

Definition

The coulomb is the SI base unit of electric charge, representing the amount of electric charge transported by a constant current of one ampere flowing for one second. It is named after French physicist Charles-Augustin de Coulomb.

History/Origin

The coulomb was first defined in 1881 by the International Electrical Congress and became part of the SI system in 1960. It honors Charles-Augustin de Coulomb (1736-1806), who formulated Coulomb's law describing the electrostatic force between charged particles.

Current Use

Coulomb is the fundamental unit for measuring electric charge in physics, engineering, and electronics. It's used in calculations involving capacitance, electric fields, and electromagnetic phenomena.
