Thaum lub zog hluav taws xob voltage kis dhau los ntawm ib kab lossis lwm yam kev sib dhos, ib feem ntawm qhov voltage yuav tau noj thiab txo. Qhov no txo qhov yog qhov hluav taws xob poob ntawm cov kab no. Qhov sib txawv ntawm qhov hluav taws xob ntawm qhov pib ntawm lub zog hluav taws xob thiab lub voltage ntawm qhov kawg taw tes yog qhov hluav taws xob poob qis. Feem ntau cov hluav taws xob hluav taws xob feem ntau ntawm USB cov ntaub ntawv cable yog qhov kev sib tw tau nug cov ntaub ntawv ntau npaum li cas los ntawm cov neeg siv khoom ntau npaum li cas thiab cov neeg ua tus coj ua loj dua. Hauv qab no yog kev piav qhia txog Volfage poob:
Voltage poob yog hais txog qhov sib txawv ntawm qhov sib txawv ntawm ob xaus ntawm cov hlau. Piv txwv li, yog tias 5V fais fab muab tau txuas nrog lub tswv yim xaus ntawm cov xaim, qhov hluav taws xob cia ntawm cov hlau no yog {}}. 2V. Yog li ntawd li cas cov voltage poob? Qhov tseeb, txawm hais tias cov khoom siv siv hauv peb cov ntaub ntawv cable yog ib tus neeg coj ua zoo, nws tsis yog superconductor tom qab tag nrho. Muaj kev tiv thaiv sab hauv. Yog li ntawd, thaum peb siv cov ntaub ntawv cable los txuas lub charger thiab lub xov tooj ntawm tes, nws yog sib npaug los txuas ib qho resistor hauv series nyob rau hauv Circuit Court. Tom qab them cov Circuit Court yog tsim, tam sim no yuav dhau los ntawm cov ntaub ntawv cable. Nrog rau lub neej ntawm kev tiv thaiv thiab tam sim no, voltage yuav ib txwm tsim ntawm ob qho kawg ntawm cov xaim, thiab tus nqi ntawm cov hluav taws xob no yog qhov ntsuas hluav taws xob.
Vim li cas thiaj yog voltage poob ib lo lus tseem ceeb rau kev txiav txim siab them nyiaj ua haujlwm? Yog vim hais tias thaum lub sijhawm them nyiaj, cov tswv yim hluav taws xob ntawm lub davhlau ya nyob twg yog ua tiav los ntawm "volfage poob" ntawm cov ntaub ntawv kab. Piv txwv li, thaum lub charger Voltage yog 5V thiab lub nqi them nrog lub cav hluav taws xob ntawm lub davhlau ya nyob twg yog 4.8V thiab tag nrho cov tswv yim Lub Hwj Chim yog 9.6W; Thiab thaum siv cov ntaub ntawv kab nrog lub voltage poob ntawm {8}}. 4W}. 2W, thiab cov hlau nqa ib qho ntxiv { {15}}. 4W poob. Qhov qis dua cov hwj huam tawm, qeeb qeeb lub tsheb nrawm. Qhov no yog qhov laj thawj tseem ceeb vim li cas cov xaim hluav taws xob tuaj yeem cuam tshuam rau kev them nyiaj ua haujlwm.
