E.2.0 Units of measurement in electrics
E.2.1 Electric current / Current intensity
As a rule, electric current is understood to mean the directed motion of charge carriers.
- The charge carriers may be both electrons and ions.
- An electric current can only flow when sufficient charge carriers are available
and freely moveable.
-The current intensity (I) serves the numerical description of the electric current.
- The more electrons that flow through a conductor in one second, the higher the
current intensity.
The symbol for current intensity is I.
Units of measurement: kA (kiloampere), A (ampere), mA (milliampere), µA (microampere),
nA (nanoampere)
The Ampere (A) is the basic SI unit (SI = International System of Units).
The ampere is named after Andre Marie Ampere.
