ampere
A
  • SI elektrivoolu ühik, mis võrdub sellise konstantse vooluga kahes sirges lõpmata pikas ja tühise ümara ristlõikega paralleelses vaakumis vahekaugusega 1 meeter paiknevas juhis, mis tekitab nende juhtide vahel jõu 2 × 10^–7 njuutonit meetri kohta
  • the ampere is that constant electric current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in a vacuum, would produce between these conductors a force equal to 2 × 10^−7 newton per metre of length
  • a unit of electric current flow equivalent to the motion of 1 coulomb of charge or 6.24 X 10[18 th power] electrons past any cross section in 1 second

  • analoogne Gibbsi energiaga, kus entalpia on asendatud sisemise energiaga (vt vabaenergia; vrd Helmholtzi vabaenergia)
    Good to know
    • Helmholtzi vabaenergia avaldub valemina A = U - TS, kus U - sisemine energia, T - absoluutne temperatuur, S - entroopia. Leiab kasutust füüsikute poolt.
  • similar to Gibbs free energy but with internal energy substituted for entalphy (see: free energy; compare: Gibbs free energy)
    Good to know
    • Is defined in contast as A = U - TS, where U - internal energy, T - absolute temperature, S - the entropy. Its utility by physicist.
