Hnub Ci Inverter Ib Theem Inverter

FT series: hnub ci inverter ib theem inverter

Nyob rau hauv lub Tsib Hlis 1825 Ohm luam tawm nyob rau hauv nws thawj scientific daim ntawv qhov lwj ntawm lub electromagnetic quab yuam uas ua los ntawm cov hluav taws xob tam sim no raws li ib tug muaj nuj nqi ntawm qhov ntev ntawm cov hlau, ib daim ntawv ntawm Galvanic circuits, tab sis cov mis nyob rau hauv nws yog tsis ncaj ncees lawm.

Thaum lub Plaub Hlis Ntuj xyoo 1826, Ohm tau kho qhov yuam kev no thiab tuaj nrog lub npe nrov Ohm txoj cai.

Xyoo 1827, nws tau luam tawm nws phau ntawv nto moo tshaj plaws, "Mathematical Treatise on Galvanic Circuits", uas nws tau teev cov qauv, qhia meej tias qhov loj ntawm tam sim no nyob rau hauv Galvanic Circuit Court yog proportional rau tag nrho cov voltage thiab inversely proportional rau tag nrho cov tsis kam ntawm. Lub voj voog, cov qauv ntawm lawv, S yog qhov siv tam sim no (I) hauv tus neeg xyuas pib, A yog qhov hluav taws xob hla tus neeg xyuas pib (U), thiab L yog qhov tsis kam (R) ntawm tus neeg xyuas pib. Nws tuaj yeem pom tias qhov no yog Ohm txoj cai qauv rau qee lub voj voog niaj hnub no.

Xyoo 1876, James Maxwell thiab nws cov npoj yaig tau tsim ntau txoj kev sim rau kev sim Ohm txoj cai, uas tshwj xeeb tshaj tawm cov lus teb ntawm cov hluav taws xob hluav taws xob rau cov cua sov.

Hauv kev sim yav dhau los, Ohm siv lub pob hluav taws xob, uas muaj lub zog hluav taws xob tsis ruaj khov uas ua rau nws mob taub hau. Tom qab ntawd, nws tau hais tias bismuth-tooj ​​liab thermocouple tau siv los ua lub zog hluav taws xob los xyuas kom muaj kev ruaj ntseg ntawm lub zog hluav taws xob ntawm lub zog hluav taws xob.
