Unit GA
Name gigaampere
Category Electric Current
Details A gigaampere (GA) is a unit of electric current in the International System of Units (SI). It represents one billion (1,000,000,000) amperes. An ampere (A) is the base unit of electric current and is defined as the flow of one coulomb of electric charge per second.

Gigaampere is a very large unit of electric current that is typically used for describing extremely high currents found in certain scientific research applications, like in particle accelerators, fusion research, or large-scale power transmission systems where currents of the order of billions of amperes can sometimes be produced or handled.

In summary, 1 GA equals 1,000,000,000 A, and it is used to measure extremely high electric currents.
