The henry (symbol: H) is the SI unit of inductance. It is named after the American scientist Joseph Henry.

Definition

---

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.

1 H = Wb/A = 1 m²·kg·s^–2·A^–2 = 1 V·s/A
