The name of the unit, Ampere (A), comes from the name of the French scientist André-Marie Ampère. This way the great scientist was given an honour for his outstanding contribution to the development of electricity and magnetism. He conducted significant research in the field of mathematics, mechanics and physics. He is considered the founder of thermodynamics. His discovery that a wire that carries electrical current can attract or repel another adjacent wire also carrying electrical current was considered revolutionary. Ampere also formulated the Ampere’s Law of electromagnetism, giving the best definition of electrical current of his time.
