direct current variant
  • 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.

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.
