Ω
  • elektritakistuse ühik SI-s
  • a unit for measuring electrical resistance
  • the electric resistance between two points of a conductor when a constant difference of potential of 1 volt, applied between these two points, produces in this conductor a current of 1 ampere, this conductor not being the source of any electromotive force
oom
Usage examples
  • Kõik ohtlikus tootmisüksuses paiknevad tehnoloogilised seadmed ja esemed, kus on võimalik staatilise elektrilaengu tekkimine, peavad olema valmistatud metallist või elektrijuhtivast materjalist (eritakistus mitte üle 105 oom/m) ja maandatud. Seadmete jadamaandus on keelatud. Seejuures ei tohi metallesemete maandustakistus ületada 20 oomi.
