词汇 | farad |
词源 | farad; faraday. Born into extreme poverty, he had virtually no formal education and is said to have possessed a very poor memory, yet Michael Faraday (1791–1867) became probably the world’s greatest experimental genius in the physical scienc- es. As both a physicist and chemist Faraday became one of the immortals of science—discovering the principle of the electric motor, developing the first dynamo, formulating the laws of electrolysis, producing the first stainless steel, and discovering benzene and butylene, among many other brilliant accomplish- ments. His discovery of electromagnetic induction alone pro- vided the basis for our modern electrified world and produced his “field concept,” which in turn was the basis a century later of Einstein’s revolutionary theory of relativity. The farad named for the scientist is an electromagnetic unit, while a faraday is a unit of electricity used in electrolysis. Faraday invented the electrical terms “anode” and “cathode.” |
