Henry (inductance) (original) (raw)

The henry (symbol H) is the SI unit of inductance. If the rate of change of current in a circuit is one ampere per second and the resulting electromotive force is one volt, then the inductance of the circuit is one henry.

The henry has dimensions V�A-1�s = m²�kg�s-2�A-2 in SI units.

The unit is named after the American scientist Joseph Henry.
