The ampere ( , ; symbol: A), often shortened to amp, 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. It is named after French mathematician and physicist André-Marie Ampère (1775–1836), considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted.
An ampere (or amp) is the standard unit used to measure the amount of electric current flowing through something, defined as one coulomb of charge passing a point every second. It matters because it's the internationally agreed-upon way to quantify electrical flow, making it essential for understanding and working with electricity in everyday applications from household devices to industrial systems.
