| Tsis zoo li cov cuab yeej ntsuas hluav taws xob, cov ntsuas hluav taws xob yuav tsum tau ntsib nrog lub zog hluav taws xob txhawm rau ua haujlwm. Voltage testers muaj hlau sojntsuam uas tau muab tso rau hauv ib qho hluav taws xob Circuit Court. Qhov ntsuas hluav taws xob yog ntsuas nyob rau hauv parallel nrog lub Circuit Court, yog li tus tester tsis yog ib qho tsim nyog ntawm Circuit Court. Tsis nco qab dab tsi "parallel" txhais tau tias? Saib: Wonka Donka's Electricity Lesson. |
 | Cov ntsuas hluav taws xob siv qhov ntsuas hluav taws xob tiag tiag thiab muab cov lej ntau rau koj los ua haujlwm nrog ntau dua li tsuas yog kuaj pom qhov muaj hluav taws xob. |
ntsuas |
| Cov ntsuas hluav taws xob tuaj yeem muab tus lej muaj tseeb yog tias lawv muaj lub vijtsam, tab sis feem ntau cov ntsuas tau ua nyob rau hauv daim ntawv ntawm LED nplai. Qhov ntsuas no yuav muab qhov ntau, tsis yog tus lej, rau qhov voltage. |
| Yog li, piv txwv li, tej zaum yuav muaj LEDs sau npe 6, 12, 24, 60, 120, 230, thiab 400. Yog li ntawd, yog tias koj ces sim ib yam dab tsi nrog ib tug voltage ntawm 30, LEDs 6,12, 24, thiab 24 yuav teeb; uas qhia tias koj muaj qhov voltage ntawm 60 thiab XNUMX. Nco ntsoov xyuas cov lus qhia rau txhua tus qauv kom pom tias nws ua haujlwm li cas. |
Cov ntsuas hluav taws xob tuaj yeem siv rau dab tsi? |
| Cov ntsuas hluav taws xob tuaj yeem siv rau ob qho tib si DC thiab AC voltage, yog li nws tuaj yeem kuaj cov roj teeb nrog lub ntsuas hluav taws xob. Zoo ib yam li lub ntsuas hluav taws xob, cov cuab yeej no tuaj yeem siv los ntsuas qhov hluav taws xob qhov hluav taws xob thiab cov hluav taws xob hluav taws xob. Txawm li cas los xij, lawv tuaj yeem txheeb xyuas qhov txuas ntxiv thiab polarity vim tias lawv muaj ob qhov kev sojntsuam thiab muaj kev sib cuag nrog lub voj voog. |
