In another variant of the CGS system, electromagnetic units (EMU), current is defined via the force existing between two thin, parallel, infinitely long wires carrying it, and charge is then defined as current multiplied by time.
The abampere was coherent with the emu-cgs system, in contrast to the ampere, the practical unit of current that had been adopted too in 1875. The emu-cgs (or "electromagnetic cgs") units are one of several systems of electromagnetic units within the centimetre–gram–second system of units ; others include esu-cgs, Gaussian units , and ...
In the cgs-emu system, the unit of electric current is the abampere. The unit of current in the Heaviside–Lorentz system doesn't have a special name. The other units in the cgs-esu and Gaussian systems related to the statampere are: statcoulomb – the charge that passes in one second through any cross-section of a conductor carrying a steady ...
This system is the most common of the several electromagnetic unit systems based on the centimetre–gram–second system of units (CGS). It is also called the Gaussian unit system, Gaussian-cgs units, or often just cgs units. [a] The term "cgs units" is ambiguous and therefore to be avoided if possible: there are several variants of CGS, which ...
The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). [1] [2] It is defined to be equal to the electric charge delivered by a 1 ampere current in 1 second. It is used to define the elementary charge e. [2] [1]
The unit was announced during the General Conference on Weights and Measures in 1960 and ... used in the CGS system. Thus, 1 G = 10 −4 T = 100 ... the current (2009 ...
The statcoulomb (statC), franklin (Fr), or electrostatic unit of charge (esu) is the unit of measurement for electrical charge used in the centimetre–gram–second electrostatic units variant (CGS-ESU) and Gaussian systems of units. In terms of the Gaussian base units, it is
The unit was established by the IEC in the 1930s [4] in honour of Danish physicist Hans Christian Ørsted.Ørsted discovered the connection between magnetism and electric current when a magnetic field produced by a current-carrying copper bar deflected a magnetised needle during a lecture demonstration.
