Ampere

Definition

The Ampere (A) is the SI base unit of electric current, defined as one coulomb of electric charge passing through a conductor per second. It is fundamental in electrical engineering and physics for measuring the rate of electric charge flow in circuits, essential for analyzing electrical systems and designing electronic devices.

History/Origin

Named after André-Marie Ampère, a French physicist and mathematician who made significant contributions to electromagnetism in the early 19th century. The ampere was officially adopted as the SI base unit for electric current in 1948, replacing earlier definitions based on electrochemical processes and providing a more precise and reproducible standard.

Current Use

The ampere is universally used in electrical engineering, electronics, and physics to measure current flow in circuits, power systems, and electronic devices. It is essential for circuit analysis, electrical safety calculations, power system design, and the specification of electrical components and equipment in industrial, commercial, and residential applications.

CGS e.m. unit

CGS em

Definition

The CGS electromagnetic unit of current is a unit in the CGS electromagnetic system, equal to 10 amperes. It was used in electromagnetic measurements and calculations before the adoption of the SI system, providing a coherent unit for electromagnetic phenomena in scientific research.

History/Origin

The CGS electromagnetic unit was part of the CGS electromagnetic system developed in the late 19th century, providing a coherent set of units for electromagnetic measurements. The abbreviation "e.m." stands for "electromagnetic," distinguishing it from electrostatic units in the CGS system.

Current Use

The CGS electromagnetic unit of current is rarely used in modern practice, having been replaced by the SI ampere.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