Several treatises by Ampere give him high place in the development of the science of electricity. His most renowned work is a Collection of Observations on Electro Dynamics, 1822. Ampere's discoveries in the field of science were remembered by giving his name to the unit of electrical current. An ampere is the current corresponding to an electromotive force of one volt moving through an ohm of resistance. It is about the current of a Daniell cell through thirty-nine feet of No. 24 copper wire.
