  • elektrivoolu ajaline integraal miinimumväärtusega e (elementaarlaeng, prootoni laeng)
  • integral of the electric current over time; the smallest electric charge found on its own is the elementary charge, e, the charge of a proton

  • skalaarsuurus, iseloomustamaks mis tahes osakese ja üldiselt mis tahes osakeste süsteemi elektromagnetilisi vastastikmõjusid
    Good to know
    • Laetud kondensaator ei ole elektriliselt laetud keha, millel on positiivne või negatiivne elektrilaeng ning sel põhjusel on elektrilaeng vooluahela teoorias määratletud kui klemmi elektrivoolu ajaline integraal.
  • ISQ tuletatud suurus
  • additive scalar quantity, attributed to any particle and, generally, any system of particles, to characterize its electromagnetic interactions
    Good to know
    • A charged capacitor is not an electrically charged body carrying a positive or negative electric charge, and for this reason, the electric charge is defined in circuit theory as the time integral of the electric current at a terminal.
  • ISQ derived quantity
elektrilaeng preferred
Usage examples
  • Elektrilaeng on alati elementaarse elektrilaengu lahutamatu kordne ja võib olla positiivne, negatiivne või null ja mis tahes osakeste süsteemi elektrilaeng on täpselt võrdne osakeste laengute summaga.
Good to know
  • Elektrilaengud alluvad Coulombi seadusele. Elektrivool läbi pinna on selle pinna kaudu ülekantud elektrilaengu ajaline tuletis. Elektrilaengu SI erinimetuse ja -tähisega koherentne tuletatud ühik on kulon, C. Ühikut amper-tund kasutatakse elektrolüütiliste seadmete puhul, näiteks akude puhul: 1 A·h = 3,6 kC.
laeng
electric charge preferred
Usage examples
  • Electric charge is always an integral multiple of the elementary electric charge, except for quarks, and can be positive, negative, or zero. Owing to additivity, electric charge for any system of particles is exactly equal to the sum of their charges.
Good to know
  • Electric charges obey Coulomb's law. The electric current through a surface is the time derivative of the electric charge transferred through that surface. The coherent SI unit of electric charge is coulomb, C. The unit ampere hour is used for electrolytic devices, such as storage batteries: 1 A·h = 3,6 kC.
