The term 'Ampère Unit' is a unit of measurement used in electrical engineering. It is named after the French physicist Andre-Marie Ampère, who was one of the founders of the science of electromagnetism. The term is composed of three parts: 'Ohm' (3 letters), 'AMP' (3 letters) and 'Watt' (4 letters). Ohm is the unit of electrical resistance, AMP is the unit of electric current, and Watt is the unit of power. Together, these three units form the Ampère Unit, which is used to measure the strength of an electric current.
