ampere

In electricity a unit of electrical current, representing the current furnished by a potential of 1 volt (the unit of electromotive force) through 1 ohm (the unit of resistance). Ampere's law. A law to the effect that the directing force of electric currents on mobile magnets causes the latter's austral pole to deviate to the left of the current. \_A. M. Ampere, a French physicist, 1775- 183 6.]
