Kev cob qhia cov neeg ua haujlwm tshiab - chav kawm thib ob

Secondary Electricity Basics Training Notes Yuav tsum pib nrog kev nkag siab zoo txog tam sim no (DC), alternating tam sim no (AC), theem-rau-theem thiab kab-rau-kab voltages.Rau txhua lub tuam txhab uas tso siab rau cov tshuab hluav taws xob, qhov kev paub no tseem ceeb heev rau tiam, kev faib tawm thiab kev tswj hwm hluav taws xob.

Direct tam sim no yog qhov ntws ntawm tus nqi hauv ib qho kev coj mus tas li.Cov roj teeb thiab cov khoom siv hluav taws xob xws li lub laptops thiab cov xov tooj ntawm tes khiav ntawm qhov tam sim no.Alternating tam sim no, ntawm qhov tod tes, yog tas li reversing kev taw qhia.AC fais fab tuag yog siv hauv tsev thiab vaj tse los khiav cov khoom siv thiab khoom siv.

Theem voltage yog qhov sib txawv ntawm ob lub ntsiab lus hauv AC Circuit Court, ib qho yog cov hlau thiab lwm qhov yog qhov nruab nrab.Ntawm qhov tod tes, kab hluav taws xob hais txog qhov sib txawv ntawm ob lub ntsiab lus hauv AC Circuit Court, ib qho yog hlau thiab lwm qhov yog hauv av.

Txhawm rau ua kom tiav, nkag siab qhov sib txawv ntawm qhov ncaj qha tam sim no thiab qhov hloov pauv tam sim no, theem voltage thiab kab hluav taws xob yog qhov tseem ceeb ntawm kev paub txog kev siv hluav taws xob thib ob.Nws yog ib qho tseem ceeb rau txhua lub lag luam lossis cov tuam txhab uas tso siab rau lossis tsim cov tshuab hluav taws xob kom muaj kev nkag siab zoo ntawm cov ntsiab lus no kom ntseeg tau tias lawv siv cov qauv kev nyab xeeb thiab cov txheej txheem kev khiav haujlwm raug.
