direct current preferred
dc
  • ajas muutumatu suunaga kestev elektrivool
  • a current that is independent of time. By extension, a current in which the direct component is of primary importance.
  • current which flows in one direction only, although it may have appreciable pulsations in its magnitude

  • elektrivool, mille suund ajas ei muutu
  • electric current that is time-independent or, by extension, periodic current the direct component of which is of primary importance
alalisvool
Usage examples
  • Alalisvool võib olla püsiva väärtusega, nt keemilise vooluallika korral, või teataval määral pulseeriv, kui seda saadakse vahelduvvoolu alaldamisel. Pulseervool on küll ühesuunaline, kuid tema tugevus muutub perioodiliselt.
Good to know
  • Alalisvoolu korral kasutatakse lühendtermineid DC, dc või d.c.
DC preferred symbol, abbreviation
dc symbol, abbreviation
d.c. symbol, abbreviation
direct current preferred
Usage examples
  • For direct current, the abbreviations DC, dc or d.c. are used.
DC preferred abbreviation, symbol
dc abbreviation, symbol
d.c. abbreviation, symbol

direct current variant
  • arvestit läbiva elektrivoolu tugevus
  • elektrilaengute suunatud liikumine elektriahelas
  • Si-süsteemi põhisuurus
  • 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
  • SI base quantity
elektrivoolu tugevus preferred
Usage examples
  • Elektrivoolu tugevus 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.

electric current preferred
Usage examples
  • Electric 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.
