> as lemmasinternational volt In 1893, at the International Electrical Congress, a definition of the volt based on the electromotive force of a standard cell known as the Clark cell was established. This unit was known as the international volt, and was later redefined in terms of the international ampere. At the 1948 General Conference on Weights and Measures, the use of the international volt was abandoned and the volt was redefined in terms of the absolute ampere.< |
