*Henry*

The henry (symbol: H) is the SI unit of inductance. It 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. The magnetic permeability of the vacuum is 4π×10−7 H/m (henry per metre).
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.
H = m2.kg/(s2.A2) = Wb/A = V.s/A = J/(C.s)/(C/s) = J.s2/C2 = m2.kg/C2
units:
- A = amp
- V = volt
- C = coulomb
- J = Joule
- Wb = weber
- kg = kilogram
- m = meter

*Henry (inductie)*

De henry, symbool H, is de SI-eenheid voor zelfinductie en wederzijdse inductie:
1 H = 1 (V s / A) = 1 (J / a^2) = 1 (T m^2 / A)
Waarbij:
- V volt
- s seconde
- A ampère
- J joule
- T tesla
- m meter
De henry is vernoemd naar Joseph Henry.

*Henry*

In the International System of Units, the derived unit of electrical inductance; the inductance induced in a circuit by a rate of change of current of one ampere per second and a resulting electromotive force of one volt.
