absolute ampere

The ampere was originally defined as the amount of current that, during one second and when the electromotive force is one volt, passes through a conductor whose resistance is one ohm. A second definition was introduced at the 1893 International Conference of Electricians, in which the ampere was taken as the unvarying current that would deposit 0.001118000 grams of silver per second from a solution of silver nitrate in water. This quantity became known as the international ampere, while that described in the original definition was called the absolute ampere.
