"kilowatt-teev" koj pom ntawm koj daim nqi hluav taws xob qhia txog lub zog uas koj siv hauv ib hlis. Txhawm rau xam cov kWh rau ib qho khoom siv tshwj xeeb, muab qhov ntsuas hluav taws xob (watts) ntawm cov khoom siv los ntawm lub sijhawm (hrs) koj siv cov khoom siv thiab faib los ntawm 1000.
Koj suav kilowatt teev li cas?
Yuav kom tau tus naj npawb kWh, koj tsuas yog muab tus lej kW los ntawm cov teev cov khoom siv rau. Piv txwv li, ib lub cuab yeej ntsuas ntawm 1500 W uas nyob rau 2.5 teev: 1500 ÷ 1000=1.5.
Koj suav li cas kW rau kWh?
Koj suav li cas kWh vs. kW?
- Faib lub wattage los ntawm 1,000 rau xam kW: 1500 watts 1,000=1.5 kW.
- Multiply the kilowatts by the hour of daily use: 1.5 kW X 2 hours=3 kWh per day.
- Nrhiav tag nrho lub zog siv rau ib hlis (30 hnub): 3 kWh X 30 hnub=90 kWh ib hlis.
pes tsawg kW yog kWh?
1 kWh sib npaug ib teev ntawm kev siv hluav taws xob ntawm tus nqi ntawm 1 kW, thiab yog li 2 kW cov cuab yeej siv 2 kWh hauv ib teev, lossis 1 kWh hauv ib nrab. teev. Qhov sib npaug tsuas yog kW x sijhawm=kWh.
pes tsawg kWh ib hnub twg?
Raws li EIA, xyoo 2017, qhov nruab nrab txhua xyoo kev siv hluav taws xob rau Asmeskas cov neeg siv khoom hauv tsev yog 10, 399 kWh (kWh), qhov nruab nrab ntawm 867 kWh ib hlis. Qhov ntawd txhais tau hais tias qhov nruab nrab hauv tsev siv hluav taws xob kWh ib hnub twg yog28.9 kWh (867 kWh / 30 hnub).
