what does ampere measure

An ampere, or "amp" for short, is a unit of electrical current. It measures the rate of electron flow or current in an electrical conductor, and one ampere of current represents one coulomb of electrical charge moving past a specific point in one second. Physicists consider current to flow from relatively positive points to relatively negative points, which is called conventional current or Franklin current. The ampere is named after French mathematician and physicist André-Marie Ampère, who is considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted.
