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.

Yuav ua li cas xam ampere teev ntsuas ntawm roj teeb?
Tus yuam sij yog siv tus wattskoj paub suav 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 .
Watt teev efficiency yog dab tsi?
Yog hais tias qhov hluav taws xob poob yog 100 mV thaum them thiab 100 mV thaum tawm thiab yog tias ηAh ntawm 100% yog assumed, lub efficiency, piv txwv li, rau ib tug 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 lithium-ion roj teeb nrog 3.
Vim li cas lub sijhawm teev sijhawm pib ntawm 1 teev?
Nws yuav tawm hauv chav ua ntej thawj daim duab, rau cov slates, countdowns, kuaj cov cim thiab lwm yam, thaum tseem khaws cia ib qho yooj yim suav lub sij hawm khiav rau cov yees duab . Kuv yuav rov pib dua kuv lub sijhawm li cas? Xaiv cov duab hauv qhov project vaj huam sib luag >
Daim ntawv teev npe twg yog ib daim ntawv teev npe?
Ib daim ntawv teev npe yog ib daim ntawv teev cov khoom tsis tau txiav txim qhov twg txhua yam khoom muaj cov duab nraajCov mos txwv yuav yog cov cim ntawm cov ntawv sib txawv, nrog rau cov cim duab. Cov npe tsis muaj npe pab tus sau cov ntawv hauv txoj hauv kev zoo dua - muab cov npe ntawm cov khoom siv, cov npe siv cov xwm txheej, thiab lwm yam .
Rau ntau theem compressor lub polytropic efficiency yog?
Rau ntau theem compressor, qhov ua tau zoo ntawm polytropic yog kev ua haujlwm ntawm txhua theem ua ke . Dab tsi yog polytropic efficiency ntawm compressor? Polytropic efficiency yog lwm lub tswv yim ntawm kev ua haujlwm feem ntau siv hauv kev ntsuas compressor.
