Voltage yog lub zog hluav taws xob lossis lub zog hluav taws xob muaj peev xwm sib txawv ntawm ob lub ntsiab lus (feem ntau nyob rau hauv cov ntsiab lus ntawm hluav taws xob hluav taws xob) ib chav tsev ntawm tus nqi, qhia hauv volts (V). Voltage, nrog rau tam sim no thiab tsis kam, piav qhia txog tus cwj pwm ntawm electrons. Cov kev sib raug zoo raug soj ntsuam los ntawm kev siv Ohms txoj cai thiab Kirchhoff's circuit laws.
Voltage: Ib qho piv txwv ntawm lub tswv yim
Cov ntsiab lus ntawm qhov hluav taws xob, nqi, tam sim no, thiab kev tiv thaiv tuaj yeem piav qhia nrog lub thoob dej thiab lub hose txuas rau hauv qab. Cov dej sawv cev rau tus nqi (thiab kev txav ntawm electrons). Cov dej ntws los ntawm lub hose sawv cev tam sim no. Qhov dav ntawm lub hose sawv cev tsis kam; ib tug slim hose yuav muaj tsawg tshaj li ib tug dav hose. Tus nqi ntawm lub siab tsim nyob rau hauv qhov kawg ntawm lub hose los ntawm cov dej sawv cev voltage.
Yog tias koj yuav tsum nchuav ib nkas loos dej rau hauv lub thoob thaum npog qhov kawg ntawm lub hose nrog koj tus ntiv tes xoo, lub siab koj xav tiv thaiv tus ntiv tes xoo zoo ib yam li qhov voltage ua haujlwm. Lub zog muaj peev xwm sib txawv ntawm ob lub ntsiab lus - sab saum toj ntawm cov kab dej thiab qhov kawg ntawm lub hose - tsuas yog ib nkas loos dej xwb. Tam sim no cia peb hais tias koj pom ib lub thoob loj txaus kom ntim nrog 450 nkas loos dej (kwv yees txaus los ntim rau 6 tus neeg kub tub). Xav txog yam uas koj tus ntiv tes xoo yuav hnov thaum sim tuav cov dej ntawd rov qab.
Voltage (tus ua) yog dab tsi ua rau tam sim no (cov nyhuv) tshwm sim; tsis muaj qhov hluav taws xob thawb los yuam nws, yuav tsis muaj qhov ntws ntawm electrons. Tus nqi ntawm electron ntws tsim los ntawm qhov hluav taws xob yog qhov tseem ceeb nrog rau kev ua haujlwm uas yuav tsum tau ua. Ob peb 1.5 V AA roj teeb yog txhua yam koj xav tau los siv lub zog me me los tswj cov khoom ua si. Tab sis koj yuav tsis cia siab tias cov roj teeb tib yam yuav tuaj yeem khiav cov khoom siv loj uas xav tau 120 V, xws li lub tub yees lossis lub tshuab ziab khaub ncaws. Xav txog qhov tshwj xeeb ntawm qhov hluav taws xob nrog cov khoom siv hluav taws xob, tshwj xeeb tshaj yog thaum sib piv cov kev tiv thaiv kev tiv thaiv ntawm surge protectors.
Teb Chaws Asmeskas daim phiaj hluav taws xob, piv txwv li, ua haujlwm ntawm 120 V (ntawm 60 Hz), uas txhais tau tias koj tuaj yeem siv 120 V stereo receiver nrog ob tus neeg hais lus. Tab sis txhawm rau kom tib lub tso suab receiver ua haujlwm nyab xeeb hauv Australia, uas ua haujlwm ntawm 240 V (ntawm 50 Hz), koj xav tau lub tshuab hloov hluav taws xob thiab ntsaws adapter.
FAQ
txhais ntawm qhov hluav taws xob siab yog dab tsi?
Lub International Electrotechnical Commission (IEC) txhais cov hluav taws xob siab tshaj li 1, 000 volts (V) ntawm kev hloov tam sim no (AC) thiab siab dua 1, 500 V ntawm cov hluav taws xob ncaj qha (DC). Txawm li cas los xij, Kev Tswj Xyuas Kev Nyab Xeeb thiab Kev Noj Qab Haus Huv (OSHA) txiav txim siab txhua qhov hluav taws xob ntawm 50 volts lossis siab dua qhov muaj kev phom sij.
Lub ntsiab lus ntawm qhov poob qis yog dab tsi?
Ib qhov hluav taws xob poob yog qhov hluav taws xob poob vim impedance. Kev poob qis ntau dhau tuaj yeem ua rau tsis raug, tsis raug, lossis tsis ua haujlwm ntawm cov khoom siv hluav taws xob. Koj tuaj yeem pab tiv thaiv qhov poob qis siv qhov ntsuas hluav taws xob.
