Biot

Definition

The Biot (Bi) is a unit of electric current in the CGS electromagnetic system, equal to 10 amperes. Named after Jean-Baptiste Biot, it was used in early electromagnetic measurements and scientific research, though it has been largely replaced by the SI ampere in modern practice.

History/Origin

Named after Jean-Baptiste Biot, a French physicist who contributed to the understanding of electromagnetism in the early 19th century. The biot was part of the CGS electromagnetic system developed in the late 19th century, providing a coherent unit system for electromagnetic measurements before the widespread adoption of the SI system.

Current Use

The biot is rarely used in modern practice, having been largely replaced by the SI ampere. It may occasionally appear in historical scientific literature or specialized contexts where CGS units are still referenced, but contemporary electrical engineering and physics predominantly use the ampere and its decimal multiples.

ESU of current

ESU

Definition

The ESU (Electrostatic Unit) of current is a unit in the CGS electrostatic system, equal to approximately 3.335641 × 10⁻¹⁰ amperes. It represents an extremely small current and was used in electrostatic measurements and calculations before the adoption of the SI system.

History/Origin

The ESU system was developed as part of the CGS electrostatic system in the late 19th century, providing a coherent set of units for electrostatic measurements. The ESU of current was defined to maintain consistency with other electrostatic units in the system, though it has been largely superseded by the SI ampere.

Current Use

The ESU of current is rarely used in modern practice, having been replaced by the SI ampere. It may appear in historical scientific literature or specialized contexts where CGS electrostatic units are referenced, but contemporary electrical engineering and physics use the ampere and its decimal multiples exclusively.
