Nqus permittivity, feem ntau denoted ε₀ yog tus nqi ntawm qhov tseeb dielectric permittivity ntawm classical nqus tsev vacuum. Xwb nws yuav raug xa mus rau qhov permittivity ntawm qhov chaw dawb, qhov hluav taws xob tas li, los yog qhov kev faib tawm ntawm lub tshuab nqus tsev. Nws yog ib qho zoo tagnrho lub cev tas mus li.
Kev tso cai ntawm qhov chaw dawb yog dab tsi?
Qhov permittivity ntawm qhov chaw dawb, ε0, yog lub cev tsis tu ncua siv feem ntau hauv electromagnetism. Nws sawv cev lub peev xwm ntawm lub tshuab nqus tsev kom tso cai rau hluav taws xob teb Nws tseem txuas nrog lub zog khaws cia hauv qhov hluav taws xob thiab qhov muaj peev xwm. Tej zaum qhov xav tsis thoob ntau, nws muaj feem cuam tshuam nrog kev ceev ntawm lub teeb.
Vim li cas thiaj hu ua qhov chaw pub dawb?
Nws hu ua permittivity vim ntau npaum li cas cov khoom "tso cai" hluav taws xob, (los yog sib nqus hauv cov hlau nplaum) cov kab hla dhau los ntawm lawv.
txhais li cas los ntawm kev tso cai ntawm qhov chaw pub dawb?
Definition of Permittivity
Permittivity tau piav raws li qhov piv ntawm hluav taws xob hloov mus rau qhov hluav taws xob siv hluav taws xobNws yog cov cuab yeej ntawm cov khoom siv los ntsuas qhov kev tawm tsam tsim tawm los ntawm cov khoom siv thaum lub sij hawm tsim hluav taws xob tam sim no. Permittivity ntawm ib yam khoom yog sawv cev los ntawm lub cim ε.
permittivity thiab permeability ntawm qhov chaw dawb yog dab tsi?
Lub Permittivity ntsuas qhov kev tawm tsam los ntawm cov khoom siv hauv kev tsim hluav taws xob. Lub permeability ntsuas lub peev xwm ntawm cov khoom tso cai rau cov kab sib nqus ntawm cov quab yuam kom dhau los ntawm nws. … Qhov kev tso cai ntawm qhov chaw dawb yog 8.85 F / m. Lub permeability ntawm qhov chaw dawb yog 1.26 H/m
