inductance preferred
self-inductance variant
  • ISQ tuletatud suurus
  • vooluringi omadus tekitada magnetvälja
  • ISQ derived quantity
  • for an inductive two-terminal element with terminals A and B, quotient of the total flux ΨAB between the terminals by the electric current i in the element
  • the tendency of an electrical conductor to oppose a change in the electric current flowing through it
induktiivsus
Usage examples
  • Induktiivsus on defineeritud kui indutseeritud pinge ja seda põhjustava voolu muutumise kiiruse suhe, ja see on proportsionaalsuse tegur, mis sõltub vooluahela juhtide geomeetriast (nt ristlõike pindalast ja pikkusest) ning juhi ja lähedalasuvate materjalide magnetilisest läbilaskvusest.
L symbol
Usage examples
  • Induktiivsuse tähis on L. See tähis on valitud füüsik Heinrich Lenzi auks tema elektromagnetilise induktsiooni alase töö (Lenzi reegel) eest.
inductance preferred
Usage examples
  • Inductance is defined as the ratio of the induced voltage to the rate of change of current causing it, and it is a proportionality constant that depends on the geometry of circuit conductors (e.g., cross-section area and length) and the magnetic permeability of the conductor and nearby materials.
self-inductance variant
L symbol
Usage examples
  • The symbol for inductance is L, chosen in honor of the physicist Heinrich Lenz for his work on electromagnetic induction (Lenz's law).

  • antud punktis paikneva pinnaelemendi heledus selle vaatlemisel standardsest vaatlemispunktist standardi EN 13201-3 järgi
  • luminance of an elementary surface centred at a given point when viewed from the standard observation position according to the EN 13201-3
normheledus preferred
Usage examples
  • Normheledus on tavaliselt sätestatud ja hinnatud teevalgustuspaigaldise projektis.
Good to know
  • Normheledust väljendatakse kandelates ruutmeetri kohta.

L symbol
luminance normative preferred
Usage examples
  • Luminance normative is a physical measure of the brightness of a surface that emits, reflects, or passes light in a specific direction.
Good to know
  • The luminance is expressed in candela per square metre.
