n. pl. hen·rys or hen·ries (-rēz)
The unit of inductance in which an induced electromotive force of one volt is produced when the current is varied at the rate of one ampere per second.
|Henry, Joseph 1797-1878. |
American physicist who studied electromagnetic phenomena. He discovered electrical induction independently of Michael Faraday, and constructed a small electromagnetic motor in 1829. He also developed a system of weather forecasting based on meteorological observations. The henry unit of inductance is named for him.
