Ampere - Wikipedia
WEBThe ampere ( / ˈæmpɛər / AM-pair, US: / ˈæmpɪər / AM-peer; [1] [2] [3] symbol: A ), [4] often shortened to amp, [5] is the unit of electric current in the International System of Units (SI). One ampere is equal to 1 coulomb (C) moving past a point per second.

WEBThe ampere is defined first. It is an SI base unit, the only electrical unit derived from the outcome of an experiment. Next up after the ampere comes the coulomb and charge on an electron. Then we derive the rest of our favorites, the watt, the volt, and the ohm.
What is Ampere (A)? Unit of Electrical Current - Definition
WEBAn Ampere is the unit of electric current. It is named after the French physicist André-Marie Ampère (who is considered the father of electromagnetism) and used in physics and electrical and electronics engineering as a base unit in SI (International System) to measure the electric current.
AMPERE Definition & Meaning | Dictionary.com
WEBThe SI unit used to measure electric current. Electric current through any given cross-section (such as a cross-section of a wire) may be measured as the amount of electrical charge moving through that cross-section in one second.
