Ampere (a) Sainmhíniú aonaid
The ampere (A), often shortened to the amp, is a unit of electric current in the International System of Units (SI). One ampere is equal to 1 coulomb (C), or 6.241509074×1018 electrons worth of charge, moving past a point in a second (s). The ampere is named after French mathematician and physicist André-Marie Ampère (1775–1836), considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted.
