A volt-ampere yog chav tsev siv rau lub zog pom tseeb hauv hluav taws xob hluav taws xob. Lub zog pom meej sib npaug ntawm cov khoom hauv paus txhais tau tias square voltage thiab hauv paus txhais tau tias square tam sim no. Hauv cov kab hluav taws xob ncaj qha, cov khoom no sib npaug rau lub zog tiag tiag hauv watts.
Volt amps txhais li cas?
A volt-ampere (SI cim: V⋅A lossis V A; kuj VA) yog chav tsev siv rau qhov pom tseeb ntawm lub zog hluav taws xob. … Nyob rau hauv direct tam sim no (DC) circuits, cov khoom no yog sib npaug rau lub hwj chim tiag tiag hauv watts. Volt-amperes feem ntau yog siv rau kev tshuaj ntsuam alternating tam sim no (AC) circuits.
Qhov txawv ntawm lub volt amp thiab lub amp yog dab tsi?
Qhov txawv ntawm volts thiab amps yog dab tsi? … Ib qho ampere ntsuas electricity. Volts sawv cev qhov sib txawv ntawm lub peev xwm uas tsav amps kom ntws los ntawm lub kaw lus kaw. Yog li ntawd, thaum amps sawv cev rau qhov ntim ntawm cov dej, volts nqa cov dej los ntawm lub voj voog.
Qhov txawv ntawm volt amps thiab watts yog dab tsi?
Watts xa mus rau "lub zog tiag tiag," thaum volt-amperes xa mus rau "pom meej zog." Ob leeg tsuas yog qhov khoom ntawm qhov hluav taws xob (V) muab faib los ntawm amperage (A). Yog li, cov cuab yeej kos duab 3 amps ntawm 120 volts yuav raug ntsuas ntawm 360 watts lossis 360 volt-amperes.
Puas muaj pes tsawg volt hauv ib lub amp?
txhais tau tias 1 amp=120 watts. Muaj pes tsawg watts hauv 1 amp ntawm 220 volts ? Ntawm 220V, koj tau txais 220W rau 1 amp.
