Kev nkag siab impedance txhais
Tawm tswv yim impedance yog qhov sib npaug impedance ntawm kev nkag ntawm hauv Circuit Court. Ntxiv rau qhov voltage voltage U rau cov kev tawm tswv yim thiab ntsuas qhov tam sim no kuv ntawm cov lus qhia. Cov tswv yim impedance Rin yog U / I. Koj tuaj yeem xav tawm tswv yim raws li qhov kawg ntawm lub resistor. Qhov tsis kam ntawm no resistor yog lub tswv yim impedance.
