Qhov txawv ntawm W thiab Wh yog dab tsi?

Qhov no yog qhov sib txawv tseem ceeb heev thiab yuav tsum tau nco ntsoov thaum saib cov lus qhia tshwj xeeb ntawm lub chaw nres tsheb fais fab.

W los yog Watts yog lub hwj chim lossis oomph uas lub chaw nres tsheb fais fab tuaj yeem muab rau cov khoom siv lossis khoom siv. Piv txwv li, yog tias koj lub tshuab ziab plaub hau khiav ntawm 1800W AC, nws txhais tau tias koj xav tau lub zog hluav taws xob uas muaj peev xwm muab tau yam tsawg kawg 1800W (1.8kW) ntawm kev hloov tam sim no (piv txwv li, zoo li cov khoom siv hluav taws xob tsis tu ncua). Feem ntau, nws tseem tsim nyog muaj me ntsis ntawm lub taub hau saum toj no tus nqi ib yam nkaus - yog li peb xav pom zoo 2000W roj teeb pob rau cov ntaub ntawv saum toj no.

Ntawm qhov tod tes, Wh yog shorthand rau Watt Teev. Qhov no yog ib chav tsev sib txawv kiag li thiab hais txog ntau npaum li cas cia lossis lub peev xwm ntawm lub pob hluav taws xob mus pw hav zoov muaj - piv txwv li, yuav ntev npaum li cas lub hwj chim pob yuav kav ntev npaum li cas los ntawm lub xeev them tag nrho mus rau qhov khoob thaum khiav ib qho khoom siv. Piv txwv li, yog tias koj muaj qhov chaw nres tsheb fais fab ntawm 30Wh lub peev xwm qhov no txhais tau tias koj tuaj yeem khiav lossis them 30 watt (W) gadget rau 1 teev ua ntej lub hwj chim pob tawm ntawm cov kua txiv hmab txiv ntoo.

Cov pob fais fab loj tuaj yeem muaj peev xwm siab - piv txwv li iFlowPower's FP2000 muaj qhov txaus ntshai 2000Wh thiab tuaj yeem muab lub zog siab tshaj plaws ntawm 2000W rau 1 teev. Qhov no txhais tau tias yog tias koj tab tom khiav lub tshuab ziab plaub hau 1800W txuas ntxiv siv qhov chaw nres tsheb fais fab no, nws yuav kav ~ 2000/1800 = 1.11 teev lossis 66 feeb ua ntej nws khoob. Tsis ntev li ntawd, tab sis tom qab ntawd dua koj ib txwm tsuas yog siv lub tshuab ziab khaub ncaws los yog lub hwj hauv luv luv 2-3 feeb tawg.
