Yuav sim ntsuas li cas cov rhaub dej sov yog ib txoj kev zoo, thiab kev siv cov cub rhaub kuj tseem muaj cov khoom siv cua sov. Txawm li cas los xij, thaum cua sov raj ua tsis tiav thiab tsis siv, peb yuav ua li cas? Peb yuav tsum txiav txim seb cov raj cua kub zoo lossis tsis zoo?
1, nrog kev ua haujlwm ntau ntau yuav raug ntsuas tawm tsam, ob peb ohms rau kaum ntawm Ohms yog qhov zoo, ntau txhiab tus thiab siab dua, tsis zoo.
2. Raws li tus qauv tsim hluav taws xob ntawm lub tshuab hluav taws xob thiab lub raj tawm ntawm lub raj cua kub yog suav nrog r = (r sawv ntsug rau voltage, p sawv rau lub zog). Qhov tshwm sim yog qhov zoo yog tias nws yog qhov ntau dua 0 thiab tsawg dua 1000.
3, yog li ntawd, thaum ntsuas nrog OHM cov ntaub ntawv (× 10ω) ntawm multimeter, yog tias nyeem yog infinity lossis ze rau infinity, nws yog qhov qhib Circuit Court. Nyeem qhia qhov qub, tsis muaj kev puas tsuaj.
4. Hauv rooj plaub uas lub cub cua sov raj tsis muaj zog rau, saib seb puas muaj qhov pom tseeb, tawg thiab tawg ntawm lub cev raj. Yog tias tsis muaj qhov pom tseeb, trachoma, tawg thiab tawg, nws yog feem ntau zoo.
Qhov kev txiav txim siab: Yog tias muaj cov qhov pom tseeb, kev tawg thiab tawg rau ntawm lub raj cua sov steel, nws qhia tau tias lub raj cua kub tau raug puas thiab tsis tuaj yeem siv tau ib yam nkaus. Thaum cov tsis kam ntsuas ntsuas yog xoom, nws tseem qhia tau tias lub raj cua sov tsis tuaj yeem siv; Yog tias cov nplaim hluav taws xob tau dhau los thiab tus nqi tiv thaiv yog nyob rau hauv ib txwm muaj, tom qab ntawd lwm yam laj thawj yuav tsum tau pom.
Yog tias koj txaus siab rau peb cov khoom, koj tuaj yeem tiv tauj peb ncaj qha!
