henry
SI unit of inductance
The henry is the unit of electrical inductance in the International System of Units (SI), defined as 1 kg⋅m2⋅s−2⋅A−2. If a current of 1 ampere flowing through a coil produces flux linkage of 1 weber, that coil has a self-inductance of 1 henry. The unit is named after Joseph Henry (1797–1878), the American scientist who discovered electromagnetic induction independently of and at about the same time as Michael Faraday (1791–1867) in England.
