Tom qab koj tau txais lub charger lossis cov ntaub ntawv cable, koj yuav kuaj nws lub zog li cas?
Nov 02, 2021| Amps, volts, thiab watts yog txhua txoj hauv kev los ntsuas qhov sib txawv ntawm hluav taws xob. Ampere (A lossis I, sawv cev tam sim no) yog tus nqi tam sim no hauv Circuit Court, thaum voltage (V) yog lub zog ntawm cov tam sim no ntws los ntawm Circuit Court, thiab watts (W) yog tag nrho cov hluav taws xob hluav taws xob uas lub Circuit Court tso tawm ib ob. . Qhia ua 1 W=1 V × 1 A.
Yuav kom nkag siab yooj yim, koj tuaj yeem xav tias nws yog lub vaj hose. Ampere sawv cev rau qhov ceev ntawm cov dej ntws los ntawm lub hose, volts sawv cev rau qhov kev siv ntawm cov dej ntws, thiab wattage sawv cev rau cov dej ntws tawm ntawm lub hose ib ob.
Txawm hais tias lub wattage kuj sib txawv, qhov voltage feem ntau yog tsau. US tus qauv yog 120 volts. Cov khoom siv hluav taws xob uas siv ntau qhov tam sim no, xws li lub qhov cub hluav taws xob, yuav tsum tau nyob rau ntawm ib qho hluav taws xob sib cais nrog qhov hluav taws xob ntau dua. Qhov no yog vim hais tias nws yuav tsum tau ib tug ntau dua wattage, uas txhais tau hais tias nws siv ntau tam sim no nyob rau hauv ib chav tsev lub sij hawm tshaj li lwm yam khoom siv, yog li nws yuav tsum tau ib tug ntau dua voltage. Yog tias tsis muaj qhov hluav taws xob ntau dua, nws yuav tsis ua haujlwm vim nws yuav tsis muaj qhov tam sim no yuav tsum tau ua haujlwm.
Tus naj npawb ntawm kilowatts nqi rau txhua tsev neeg muaj feem xyuam rau volts thiab amperes. Lub volt tseem zoo li qub, tab sis lub ampere hloov raws li qhov kev thov tam sim no. Thaum tib neeg tig rau cov khoom siv ntau dua lossis khiav lawv ntev dua, lawv nce lawv qhov kev thov tam sim no, yog li ua kom tag nrho cov wattage noj. Los ntawm kev khiav cov khoom siv tsawg dua lossis hloov mus rau cov khoom siv tau zoo dua uas yuav tsum tau siv tam sim no tsawg dua, tib neeg tuaj yeem txo cov kilowatts siv thiab txo cov nqi hluav taws xob.
