Qhov zoo tagnrho resistor zoo li

Nyob rau hauv ib qho zoo tagnrho resistor, tus nqi kuj yuav tsis hloov nrog voltage lossis tam sim no, thiab nws yuav tsis hloov vim tam sim no hloov tam sim no. Cov resistors tiag tiag tsis tuaj yeem ua tiav qhov no. Niaj hnub no cov qauv tsim sab hauv tso cai rau cov resistors tuaj yeem pom cov kev hloov pauv me me hauv cov nqi tiv thaiv nyob rau hauv qhov hluav taws xob tsis tshua muaj hluav taws xob lossis tam sim no (thiab txawm tias lwm yam xwm txheej ib puag ncig xws li kub).

Qhov tseeb Resistor txwv

Txhua tus resistor muaj qhov txwv siab tshaj ntawm qhov voltage lossis tam sim no nws tuaj yeem tiv taus (nyob ntawm qhov loj ntawm qhov resistor). Yog hais tias qhov voltage los yog tam sim no ntau tshaj qhov no, thawj tus nqi ntawm cov resistor yuav hloov (nyob rau hauv ib co resistors muaj peev xwm yuav hloov heev), thiab ces tus resistor yuav puas los ntawm overheating thiab thiaj li nyob. Feem ntau cov resistors yuav raug cim nrog lub zog hluav taws xob ntsuas, thaum lwm tus yuav muab qhov ntsuas tam sim no lossis qhov hluav taws xob.

Tsis tas li ntawd, qhov tseeb resistor nws tus kheej muaj me me ntawm inductance lossis capacitance ntxiv rau qhov tsis kam, uas ua rau nws qhov kev ua tau zoo sib txawv ntawm qhov zoo tagnrho resistor.
