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of current was defined to maintain consistency with other electrostatic units in the system, though it has been largely superseded by the SI ampere.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The ESU of current is rarely used in modern practice, having been replaced by the SI ampere.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.

Abampere

abA

Definition

The Abampere (abA) is a unit of electric current in the CGS electromagnetic system, equal to 10 amperes. It was part of the absolute electromagnetic system of units used in scientific measurements before the adoption of the SI system, representing a coherent unit for electromagnetic calculations.

History/Origin

The abampere was part of the CGS electromagnetic system developed in the late 19th century, providing a coherent set of units for electromagnetic measurements. The prefix "ab" stands for "absolute," distinguishing it from other current units in the CGS system and emphasizing its role in absolute electromagnetic measurements.

Current Use

The abampere is largely obsolete in modern practice, having been replaced by the SI ampere. It may occasionally be encountered in historical scientific literature or specialized academic contexts where CGS electromagnetic units are discussed, but contemporary electrical engineering uses the ampere and its decimal multiples exclusively.
