  • induktiivsuse erinimetusega SI tuletatud ühiku nimetus/tähis
  • name/symbol of the SI derived unit with special name for inductance
henri
Usage examples
  • Üks henri on selline induktiivsusühik, mille korral tekib ühe voldi suurune pinge, kui elektrivool muutub kiirusega üks amper sekundis. Ühik on nimetatud Ameerika teadlase Joseph Henry järgi, kes avastas elektromagnetilise induktsiooni sõltumatult ja umbes samal ajal kui Michael Faraday Inglismaal.
Good to know
  • Erinimetusega induktiivsuse SI tuletatud ühik henri on määratletud ühikuvõrrandiga H ≔ Wb/A, kus Wb ja A on vastavalt ühikute veeber ja amper tähised.
H symbol
Usage examples
  • 1 H = 1 Wb/A.
henry
Usage examples
  • One henry is the amount of inductance that produces a voltage of 1 volt when the electric current changes at a rate of 1 ampere per second. Named after Joseph Henry, the American scientist who discovered electromagnetic induction independently and around the same time as Michael Faraday in England.
Good to know
  • Coherent SI unit of inductance and permeance, defined by the unit equation H ≔ Wb/A, where Wb and A are weber and ampere, respectively.
H symbol
Usage examples
  • 1 H = 1 Wb/A.
