ESU of Charge

ESU

Definition

ESU (Electrostatic Unit) of charge is a unit in the CGS electrostatic system, equal to approximately 3.335640951982E-10 coulombs. It represents the electrostatic unit of electric charge.

History/Origin

ESU of charge was part of the CGS electrostatic system of units, defined based on electrostatic principles and the force between charged particles.

Current Use

Historical unit rarely used in modern applications. The coulomb and other SI units have replaced the CGS electrostatic system in most scientific and engineering work.

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.
