thaum koj qhib thiab kaw qhov ammeter , cov khoom siv hlau nplaum ncig yuav khaws cov inductance amplifies lawv mus rau qhov hluav taws xob uas tsav lub ntsuas. Ntau dua qhov tam sim no, qhov voltage ntau dua. Yog li koj tuaj yeem tau txais kev ncaj ncees nyeem ntawv ntawm tam sim no ntws hauv a kaw Circuit Court.

Hais txog qhov no, yuav ua li cas rau kev nyeem ntawv ntawm lub ammeter thaum lub qhov qhib qhib?

Thaum lub hloov tau qhib , resistors R1 thiab R2 yog nyob rau hauv series, thiaj li hais tias tag nrho Circuit Court kuj yog loj dua thaum lub hloov raug kaw. Raws li qhov tshwm sim, tam sim no txo qis, txij li qhov muaj peev xwm sib txawv tau kho.

Tsis tas li ntawd, dab tsi tshwm sim rau kev nyeem ntawv ntawm lub ammeter thaum koj ntxiv qhov muag teev ntxiv nyob rau hauv qhov sib npaug? Nyeem ntawv ntawm ammeter (A) As ntau qhov muag teev muaj kev cob cog rua hauv thaum uas tig mus , lub zog tam sim no yuav tsum tau nce vim qhov kev tiv thaiv tag nrho ntawm lub voj voog qis. Qhov no txhais tau hais tias daim duab yuav tsum yog txoj kab ncaj nraim nrog kev nce ntxiv.

Ntawm no, nyeem ammeter yog dab tsi?

Nws yog ib qho cuab yeej uas pab ntsuas ammeter tam sim no hauv Circuit Court. Los ntawm Ammeter nyeem ntawv peb txhais tau tias nyeem ntawv qhov deflection ntawm rab koob magnetic uas tshwm sim vim qhov kev siv ntawm lub magnetic teb uas tshwm sim nyob rau hauv lub ammeter coil vim yog tus nqi tam sim no ntws.

Dab tsi yog txhais los ntawm 1 ampere?

Ib ampere yog ib chav ntsuas ntawm tus nqi ntawm electron ntws los yog tam sim no nyob rau hauv ib tug hluav taws xob conductor. Ib ampere ntawm tam sim no sawv cev ib coulomb ntawm hluav taws xob nqi (6.24 x 1018 tus nqi thauj khoom) txav dhau los ntawm qhov tshwj xeeb hauv ib thib ob. Cov ampere muaj npe tom qab Andre Marie Ampere , Fabkis physicist (1775-1836).
