Txhua yam khoom siv hluav taws xob siv nyob rau hauv lub tsev thaiv hluav taws xob tuaj yeem, nyob rau hauv qee qhov xwm txheej, kis tau tus neeg tuag tam sim no . Thaum twg tus nqi ntawm tam sim no tshaj 10 milliamps (0.01 amp) muaj peev xwm ua rau mob hnyav rau kev poob siab, dej ntws nruab nrab ntawm 100 thiab 200 mA (0.1 txog 0.2 amp) yog tuag taus.

Raws li, dab tsi yog qhov txaus ntshai voltage lossis tam sim no?

Ib qho hluav taws xob tam sim no ntawm 1,000 volts tsis muaj kev tuag ntau dua li ib tam sim no ntawm 100 volts, tab sis me me hloov nyob rau hauv amperage txhais tau hais tias qhov sib txawv ntawm txoj sia thiab kev tuag thaum ib tug neeg tau txais hluav taws xob poob siab.

Kuj Paub, qhov twg tam sim no txaus ntshai? Ib qho laj thawj uas AC yuav raug txiav txim siab txaus ntshai dua yog nws arguably muaj ntau txoj kev nkag mus rau hauv koj lub cev. Txij li thaum qhov hluav taws xob hloov pauv, nws tuaj yeem ua rau tam sim no nkag mus thiab tawm ntawm koj lub cev txawm tias tsis muaj lub voj kaw, vim tias koj lub cev (thiab qhov av nws txuas nrog) muaj peev xwm. DC ua tsis tau li ntawd.

Yog li ntawd, DC tam sim no puas tuaj yeem tua koj?

Hais txog cov neeg tuag, ob qho tib si tua tab sis ntau milliamps yuav tsum tau DC tam sim no tshaj AC tam sim no ntawm tib qhov voltage. Txawm tias ob qho tib si AC thiab DC tam sim no thiab poob siab yog tuag taus, ntau dua DC tam sim no yuav tsum muaj cov nyhuv tib yam li AC tam sim no.

Puas yog volts lossis amps tua koj?

Yog li, rov qab mus rau qhov twg tua koj , cov cov amps los yog hluav taws xob . Muab koj lub cev yog ib qho kev tiv thaiv tsis tu ncua, nws yeej yog kev sib txuas ntawm ob qho tib si. High voltage txhais tau tias siab dua amperage, thiab yog li siab dua voltage muaj peev xwm ntau dua tua . Nws tsuas siv 100mA kom nres koj lub plawv.
