The ampere, often shortened to amp, measures the rate of electron flow in a circuit. It is named after André-Marie Ampère, one of the founders of classical electromagnetism. Interestingly, just one single ampere represents about six quintillion electrons passing through a specific point every second! Photo: Hannes Grobe (talk), Wikimedia Commons, CC BY 3.0.
