The henry (symbol: H) is the SI unit of inductance. It is defined as the inductance of a closed circuit in which a change of current of one ampere per second induces an electromotive force of one volt. The unit is named after American engineer Joseph Henry, who made significant contributions to the study of electromagnetism in the 19th century.
