Also known as H

SI unit of inductance

AI overview

Henry is the standard unit of measurement for electrical inductance, which describes how strongly a component in an electrical circuit resists changes in electric current. It matters because it allows engineers and scientists to precisely specify and communicate the inductance properties of electrical devices like coils, transformers, and inductors.

Encyclopedic overview

The henry (symbol: H) is the unit of electrical inductance in the International System of Units (SI), defined as 1 kg⋅m⋅s⋅A. 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.
