Ntsiab Qhov txawv ntawm Volt thiab Amp.

Cov hluav taws xob yog lub peev xwm txawv , hluav taws xob thiab electromotive quab yuam, whereas lub amp yog qhov ntsuas tam sim no. Cov hluav taws xob yog ntsuas los ntawm voltmeter whereas tus amp yog ntsuas los ntawm ammeter.

Ib yam li ntawd, tib neeg nug, pes tsawg volts nyob hauv ib lub amp?

12 Volt

Tsis tas li ntawd, qhov txawv ntawm volt watt thiab ampere yog dab tsi? Watts xa mus rau "lub zog tiag," thaum hluav taws xob - amperes xa mus rau "pom meej lub zog." Ob leeg tsuas yog cov khoom ntawm voltage (V) multiplied by amperage (A). Yog li, ib qho kev kos duab 3 cov amps ntawm 120 hluav taws xob yuav raug ntsuas ntawm 360 watts lub 360 hluav taws xob - amperes.

Cov lus nug tseem yog, puas volts lossis amps tua koj?

Yog li, rov qab mus rau qhov twg tua koj , cov cov amps los yog hluav taws xob . Muab koj lub cev yog ib qho kev tiv thaiv tsis tu ncua, nws yeej yog kev sib txuas ntawm ob qho tib si. High voltage txhais tau tias siab dua amperage, thiab yog li siab dua voltage muaj peev xwm ntau dua tua . Nws tsuas siv 100mA kom nres koj lub plawv.

Muaj pes tsawg amps yog 220 volts?

20amps ua
