Tus yuam sij yog siv cov watts koj paub los xam cov amps ntawm lub roj teeb voltage. Piv txwv li, hais tias koj xav khiav lub teeb 250 watt 110VAC ntawm lub inverter rau 5 teev. Amp-teev (ntawm 12 volts)= watt-teev / 12 volts=1470 / 12=122.5 amp-teev.
Koj suav li cas amp teev efficiency?
Yog tias qhov hluav taws xob poob qis yog 100 mV thaum lub sijhawm them thiab 100 mV thaum lub sijhawm tso tawm thiab yog tias η Ahntawm 100% yog xav, efficiency, piv txwv li, rau Ni-Cd cell nrog 1.2 V nominal voltage yog ηWh=ηU=1.1 V/1.3 V=84.6%. Hauv kev sib piv nrog cov roj teeb lithium-ion nrog 3.6 V nominal voltage, qhov ua tau zoo yog ηWh=ηU=3.5 V / 3.7 V=94.6 %
Ampere-teev efficiency yog dab tsi?
Los ntawm International Dictionary of Marine Aids to Navigation. 6-5-145. Qhov piv ntawm ampere-teev tso zis tau muab thaum lub sij hawm tso tawm ntawm ib tug thib ob cell los yog roj teeb rau lub ampere-teev input yuav tsum tau thaum lub sij hawm them nqi, raws li tau teev tseg tej yam kev mob.
Ampere-teev mis mis yog dab tsi?
Amp-teev yog xam los ntawm muab cov lej ntawm amps (A) lub roj teeb muab los ntawm lub sijhawm tso tawm hauv teev (h). Yog li, yog tias lub roj teeb muab 10 amps tam sim no rau 10 teev, nws yog 10 amps × 10 teev=100 Ah roj teeb.
Koj suav li cas watt teev efficiency?
Peb paub tias, watt teev efficiency yog piv ntawm cov khoom ntawm qhov hluav taws xob tawm thiab tawm tam sim no rau cov khoom ntawm kev them nqi hluav taws xob thiab them tam sim no. Yog li, tag nrho watt teev efficiency yog ib txwm tsawg tshaj li ampere teev efficiency.
