The SI unit of
ampere is simply
ampere (symbol:
A).
It is the unit used to measure electric current. One ampere is defined as the flow of
one coulomb of charge per second. In other words, if a current of 1 ampere flows through a conductor, 1 coulomb of electric charge passes through a cross-section of the conductor every second.
The ampere is one of the seven base units in the International System of Units (SI).
