Qhov sib txawv ntawm multimeters siv cov ntaub ntawv tsis kam, tam sim no thiab voltage
1. Resistance iav: Kho lub multimeter raws li lub hwj chim mov thiab lub voltmeter, txuas lub multimeter thiab Circuit Court nyob rau hauv series, muab ib tug tej yam voltage rau lub Circuit Court nyob rau hauv kev sim, thiab ces coj mus kuaj tam sim no ntawm lub Circuit Court tom qab ntxiv load. Li no, tus nqi kuj ntawm sab Circuit Court yog xam. (Ceeb Toom: Circuit Court yuav tsum tsis txhob siv rau lub sij hawm xeem)
2. Cov iav tam sim no: Zoo ib yam li ammeter, txuas lub multimeter rau hauv Circuit Court hauv series los ua ib lub voj. Lub Circuit Court yog powered. Nco ntsoov sim hauv qhov ntau. Txwv tsis pub nws yog ib qho yooj yim mus hlawv.
3. Voltage iav: zoo ib yam li lub voltmeter, txuas nyob rau hauv parallel mus rau ob hnub ntawm lub Circuit Court nyob rau hauv kev ntsuam xyuas, lub Circuit Court yuav tsum tau powered los ntsuas qhov voltage.
Yog tias koj ntsuas cov hlau ntev heev, koj yuav tsum txiav txim siab li cas?
Puas yog cov kab ntev txuas ua ke thiab muab tso rau ntawm koj sab? Yog tias tsis yog, nws yog qhov nyuaj los ntsuas nrog lub multimeter. Yog tias nws tau muab tso rau ntawm koj sab, txuas 2 qhov kawg ntawm cov hlua khi mus rau 2 lub ntsuas ntsuas ntawm lub tshuab ntsuas, thiab lub tshuab multimeter tuaj yeem tig mus rau "cov iav tiv thaiv" txog 2K.
