3000w Pure Sine Wave Off Grid Inverter

GI series: 3000w Pure Sine Wave Off Grid Inverter

Kev sib raug zoo nrog electromagnetism yog classical electrodynamics, thiab tsis muaj qhov sib txawv ntawm txoj cai ntawm ob. Feem ntau hais lus, electromagnetism tsom mus rau kev sim kev tshawb fawb ntawm electromagnetic phenomena, thiab qhia txog cov kev cai yooj yim ntawm electromagnetism los ntawm kev tshawb fawb dav dav ntawm electromagnetic phenomena; classical electrodynamics tsom rau qhov theoretical nam, uas yog raws li Maxwell qhov sib npaug thiab Lorentz quab yuam. , los kawm txog kev faib khoom ntawm electromagnetic teb, excitation, hluav taws xob thiab propagation ntawm electromagnetic nthwv dej, thiab kev sib cuam tshuam ntawm cov nqi hais nrog electromagnetic teb thiab lwm yam teeb meem electromagnetic. Nws tseem tuaj yeem hais tau tias cov khoom siv hluav taws xob dav dav suav nrog classical electrodynamics.

Rau kev cuam tshuam ntawm kev sib raug zoo thiab quantum txoj kev xav ntawm txoj kev loj hlob ntawm electromagnetism, saib Relativistic Electrodynamics, Quantum Electrodynamics . Tom qab Maxwell's "Electromagnetic Theory" tau luam tawm, vim hais tias txoj kev xav nyuaj rau kev nkag siab thiab tsis muaj kev sim tshuaj xyuas, nws tsis muaj nuj nqis thiab feem ntau lees paub rau lub sijhawm ntev.

Xyoo 1879, Berlin Academy ntawm Kev Tshawb Fawb tau teeb tsa ib tsab ntawv uas tau txais txiaj ntsig thov los ua pov thawj peb qhov kev xav hauv qab no: (1) Yog tias muaj kev hloov pauv tam sim no, yuav tsum muaj cov khoom sib nqus; (2) Lub zog sib nqus hloov pauv yuav tsum ua kom muaj qhov hloov pauv tam sim no hauv qhov nruab nrab insulator; (3) Hauv huab cua lossis lub tshuab nqus tsev, Ob qhov kev xav saum toj no kuj tuav. Qhov kev hu rau cov ntawv no tau dhau los ua tus thawj coj ntawm Hertz qhov kev sim electromagnetic yoj.
