Units of electric current

The unit of electric current is the ampere, often abbreviated as "A." An ampere is defined as the flow of one coulomb of electric charge per second. In the International System of Units (SI), the ampere is one of the basic units and is considered one of the seven fundamental quantities. In practical terms, an electric current of one ampere corresponds to the movement of approximately 6.

The abampere (abA) is a unit of electric current in the centimeter-gram-second (CGS) system of electromagnetic units. It is defined as the amount of current that will produce a force of one dyne on each of two long, parallel conductors that are one centimeter apart in a vacuum. In terms of the more commonly used SI units, 1 abampere is equal to 10 amperes.

Ampere, often abbreviated as "A," is the unit of electric current in the International System of Units (SI). It is one of the seven base units in the SI system and is defined as the amount of electric charge that flows through a conductor in one second when a constant current flows. To be more precise, one ampere is defined as the flow of one coulomb of charge per second.

The statampere (often abbreviated as statA) is a unit of electric current in the CGS (centimeter-gram-second) system of units, specifically in the electrostatic system. It is defined based on the electrostatic units of charge and is primarily used in contexts where electromagnetic phenomena are considered in a theoretical framework.
