Hloov ua lwm yam amps (A) mus Watts (W)

Lus qhia rau kev siv: Hloov ua lwm yam amps (Аnyob rau hauv watts (Hnub Tuesday), sau cov nqi tam sim no I hauv amperes (A), voltage U hauv volts (В), xaiv lub hwj chim factor PF los ntawm 0,1 mus rau 1 (yog tias xav tau), ces nias lub "xam”. Yog li, lub zog yuav tau txais P в Hnub Tuesday. Txhawm rau rov pib dua cov ntaub ntawv nkag, nyem lub pob sib txuas.

Tshuab xam zauv А в Hnub Tuesday (1 theem DC)

Formula rau kev txhais lus А в Hnub Tuesday

P_{Hnub Tuesday} = Kuv_А ⋅ UA_В

hwj chim P hauv watts (Hnub Tuesday) ntawm ib-theem network nrog ncaj qha tam sim no yog sib npaug rau cov khoom ntawm lub zog tam sim no I hauv amperes (А) thiab kev nyuaj siab U hauv volts (В).

Tshuab xam zauv А в Hnub Tuesday (1 theem, AC)

Formula rau kev txhais lus А в Hnub Tuesday

P_{Hnub Tuesday} = PF ⋅ I_А ⋅ UA_В

hwj chim P hauv watts (Hnub Tuesday) ntawm ib-theem network nrog alternating tam sim no sib npaug rau lub zog tam sim no I hauv amperes (А) multiplied los ntawm qhov voltage U hauv volts (В) thiab lub zog muaj zog PF.

Tshuab xam zauv А в Hnub Tuesday (3-theem, AC, kab-rau-kab voltage)

Formula rau kev txhais lus А в Hnub Tuesday

P_{Hnub Tuesday} = √3 ⋅ PF ⋅ I_А ⋅ UA_В

hwj chim P hauv watts (Hnub Tuesday) ntawm peb-theem AC network nrog kab-rau-kab hluav taws xob sib npaug ntawm lub hauv paus square ntawm peb zaug tam sim no I hauv amperes (А), voltage U hauv volts (В) thiab lub zog muaj zog PF.

Tshuab xam zauv А в Hnub Tuesday (3 theem, AC, theem voltage)

Formula rau kev txhais lus А в Hnub Tuesday

P_{Hnub Tuesday} = 3 ⋅ PF ⋅ I_А ⋅ UA_В

hwj chim P hauv watts (Hnub Tuesday) ntawm peb-theem network nrog alternating tam sim no thiab theem voltage yog sib npaug rau peb zaug cov khoom ntawm lub zog tam sim no I hauv amperes (А), voltage U hauv volts (В) thiab lub zog muaj zog PF.
