Nyob rau hauv electromagnetism, lub meej permittivity, feem ntau tsuas yog hu ua permittivity thiab denoted los ntawm Greek tsab ntawvε ( epsilon ua ), yog ib qho kev ntsuas ntawm electricpolarizability ntawm ib tug dielectric. The SI chav tsev rau permittivity is farad per meter (F/m).

Tom qab ntawd, lub tsev permittivity yog dab tsi?

Farad rau ib 'meter'

tus nqi epsilon yog dab tsi? Epsilon Naught yog synonymous rau lub permittivity ntawm qhov chaw dawb los yog kiag li permittivity los yog hluav taws xob tas li, sawv cev los ntawm Greek cov tsiaj ntawv ε0. Cov Epsilon Tsis muaj tus nqi yog tas li ntawm ib feem ntawm lub ntiaj teb. Permittivity yog qhov ntsuas ntawm qhov kev tawm tsam tau tawm tsam kev tsim hluav taws xob.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog ε0 hauv physics?

Lub cev tsis tu ncua ε0 (hais tias yog "epsilon nought" lossis "epsilon xoom"), feem ntau hu ua lub tshuab nqus tsev permittivity, permittivity ntawm qhov chaw dawb lossis hluav taws xob tsis tu ncua lossis qhov kev faib tawm ntawm lub tshuab nqus tsev, yog qhov zoo tagnrho, (hauv paus) lub cev tsis tu ncua, uas yog tus nqi ntawm qhov tseeb permittivity ntawm

SI unit ntawm txheeb ze permittivity yog dab tsi?

Qhov no qhia txog qhov sib txawv ntawm ob qho kev ntsuas ntawm kev tso cai hauv qhov sib txawv chav tsev tshuab. Hauv SI units , ε0 yog cov kev tso cai ntawm qhov chaw dawb thiab muaj tus nqiε0 ≈ 1.85 ×10-12 Farads / meter. Hauv SI units , thequantity (1 + xe) kuj hu ua txheeb ze permittivity , εr.
