  • Rahvusvahelise suuruste süsteemi ISQ põhisuurus
  • suurus, mis tähistab elektrivoolu tihedust jagatuna voolusuunalise pinnaga
  • ISQ base quantity
  • scalar quantity equal to the flux of the electric current density through a given directed surface
  • scalar quantity equal to the quotient of the net quasi-infinitesimal electric charge dQ transferred through a surface during a quasi - infinitesimal time interval and the duration dt of that interval
elektrivoolu tugevus preferred
Good to know
  • Elektrivoolu tugevus läbi pinna on võrdne ajaintervalli jooksul läbi selle pinna läbinud elektrilaengu jagatise piiriga selle intervalli kestuse järgi, kui see kestus kipub olema null, ning pinnale jäävate laengukandjate puhul määratletakse elektrivoolu tugevus läbi selle pinna kõvera.

electric current preferred
Good to know
  • The electric current through a surface is equal to the limit of the quotient of the electric charge transferred through that surface during a time interval by the duration of this interval when this duration tends to zero. For charge carriers confined to a surface, the electric current is defined through a curve of this surface (see the note to term “lineic electric current”).

  • arvestit läbiva elektrivoolu tugevus
  • elektrilaengute suunatud liikumine elektriahelas
  • electrical current flowing through the meter
  • rate of flow of electric charge past a point or region
  • flow of charged particles, such as electrons or ions, moving through an electrical conductor or space
elektrivool preferred
Usage examples
  • Elektrivool tekitab magnetvälju, mida kasutatakse mootorites, generaatorites, induktiivpoolides ja trafodes ning tavalistes juhtides põhjustab ta kuumenemist, mis tekitab valgust hõõglampides ja ajas muutuv vool kiirgab elektromagnetlaineid, mida kasutatakse telekommunikatsioonis teabe edastamiseks.

electrical current preferred
Usage examples
  • Electrical currents create magnetic fields, which are used in motors, generators, inductors, and transformers, and in ordinary conductors, they cause Joule heating, which creates light in incandescent light bulbs, and time-varying currents emit electromagnetic waves, which are used in telecommunications to broadcast information.
