Gaus txoj cai hais tias tag nrho cov hluav taws xob hluav taws xob hluav taws xob yog tias hluav taws xob tsis sib xws, hluav taws xob flux (ΦE) dhau los ntawm qhov chaw ntawm vector cheeb tsam S yog: ΦE=E⋅S=EScosθ, qhov E yog qhov loj ntawm qhov hluav taws xob (muaj units ntawm V/m), S yog thaj tsam ntawm qhov chaw, thiab θ yog lub kaum sab xis ntawm cov kab hluav taws xob thiab qhov qub (perpendicular) rau S. https://www.toppr.com › guides › physics › electric-flux
Electric Flux: Taw qhia, Gauss Law, Formula, Videos, Solved Examples
tawm los ntawm qhov ntim ntawm cov nqi sib npaug ntawm cov nqi kaw lub sijhawm tso cai ntawm qhov nruab nrab hauv qhov chaw. Yog li yog tias ∫ E. ds=0, nws txhais tau hais tias net flux los ntawm qhov chaw yog xoom piv txwv li yog tsis muaj nqi enclosing qhov nto.
Ntawm qhov chaw twg raug txiav txim siab rau Vajtswv txoj cai?
Qhov chaw uas peb xaiv rau daim ntawv thov ntawm Gauss txoj cai yog hu ua Gaussian nto.
Gauss txoj cai hais li cas?
Gauss txoj cai rau hluav taws xob hais tias cov hluav taws xob ntws hla txhua qhov chaw kaw yog sib npaug rau cov nqi hluav taws xob uas kaw los ntawm qhov chaw.
Gauss txoj cai thiab Gaussian nto yog dab tsi?
Raws li Gauss txoj cai, qhov ntws ntawm cov hluav taws xob los ntawm ib qho chaw kaw, tseem hu ua Gaussian nto, yog sib npaug rau cov nqi them uas tau muab faib los ntawm covpermittivity ntawm qhov chaw dawb: Qhov sib npaug no tuav rau tus nqi ntawm ib qho kos npe, vim tias peb txhais thaj tsam vector ntawm qhov chaw kaw kom taw qhia sab nraud.
Txoj cai Gauss puas siv tau rau txhua qhov chaw?
Gauss txoj cai muaj feem xyuam rau txhua qhov chaw kaw nrog qee qhov kev faib tawm. Gaussian nto yog qhov chaw nyob rau hauv peb seem qhov chaw uas cov kab flux ntawm ib vector teb hla.
