Ntau npaum li cas Watts Ib Kilowatt Teev?Kev hloov pauv ntawm ob yog qhov yooj yim heev
Feem ntau, thaum peb them cov nqi hluav taws xob, peb ib txwm hais tias muaj pes tsawg kilowatt-teev hluav taws xob.
Ua ntej tshaj plaws, cia peb paub ob lo lus no, ua ntej dab tsi yog lub hwj chim. Chav tsev ntawm lub hwj chim yog "watt", cim W, lub zog yog lub cev muaj nuj nqis uas qhia tias qhov khoom ua haujlwm ceev npaum li cas. Ntawm no nws tuaj yeem ua kom yooj yim raws li tus nqi hluav taws xob noj. Qhov loj dua cov ntaub ntawv cim ntawm cov khoom siv hluav taws xob, qhov ntau dua qhov kev siv hluav taws xob.
Qhov thib ob yog kev siv hluav taws xob, 1 kWh ntawm hluav taws xob, uas yog, thaum lub tshuab hluav taws xob nrog lub zog ntawm 1kw khiav rau 1 teev, peb hu nws 1 kWh ntawm hluav taws xob.
Yog li tam sim no peb tuaj yeem ua piv txwv. Yog tias lub zog ntawm lub tshuab ziab plaub hau yog 500w, thiab nws siv rau ib teev, peb tuaj yeem paub tias qhov hluav taws xob siv tau =0.5kw × 1h=0.5kwh=0.5 kWh. Siv lub tshuab ziab plaub hau rau ob teev siv 1 kWh ntawm hluav taws xob.
Ntawm qhov tsis sib xws, peb tuaj yeem qhia 1 degree ntawm hluav taws xob, uas tuaj yeem khiav lub tshuab ziab plaub hau nrog lub zog ntawm 500w rau 2 teev. 1 kWh ntawm hluav taws xob tuaj yeem khiav lub tshuab hluav taws xob hluav taws xob nrog lub zog ntawm 1000w rau 1 teev. Qhov no yog kev hloov pauv ntawm kev siv hluav taws xob thiab hluav taws xob hluav taws xob.
