Piv txwv li, Yog tias koj hloov ON lub teeb 1000 watt rau 1 teev, Nws txhais tau tias koj haus 1000 watts rau ib teev piv txwv li (1000 watts rau 1 teev = 1kWh = 1 chav tsev ntawm Zog). Yog li yog tias tus nqi ntawm chav tsev yog $5, ces koj yuav them 5 Dollars ua ib daim nqi rau koj lub teeb uas tau noj 1kWh = 1 unit ntawm hluav taws xob.
Xav txog qhov no, tus qauv rau tam sim no yog dab tsi?
Hluav taws xob tam sim no yog ib qho kev ntsuas ntawm cov dej ntws, xws li, piv txwv li, tus nqi ntws … Tam sim no isusually denoted los ntawm lub cim I. Ohm txoj cai hais txog lub tam sim no ntws los ntawm tus neeg xyuas pib mus rau qhov voltage V andresistance R; yog, V = IR. Lwm nqe lus ntawm Ohm'slaw yog kuv = V / R.
Ib yam li ntawd, kuv yuav hloov watts rau units li cas? Luas = 10 x 10 = 1000 Watt -Hour = 1 Kilowatt-Hour (kWH) = 1 units (ntawm koj lub 'meter').
Ib tug kuj yuav nug, koj ua li cas xam cov hluav taws xob?
Hluav taws xob ntsuas hauv kilowatt-teev ntawm koj daim nqi, tsis yog watt-teev. Ib kilowatt yog sib npaug rau 1,000 watts, yog li ntawd xam pes tsawg kWh ib lub cuab yeej siv, faib cov watt-teev ntawm cov kauj ruam dhau los los ntawm 1,000.
Muaj pes tsawg units yog 1kW?
1000

Yuav ua li cas koj xam lub cev muaj zog overload tam sim no?
Faib los ntawm qhov ntsuas tag nrho load tam sim no los ntawm lub npe tsav tsheb. Qhov no yuav yog qhov tseem ceeb load rau lub cev muaj zog. Yog tias lub cev muaj zog tam sim no yog 22A thiab qhov ntsuas tag nrho tam sim no yog 20A, ces qhov ntsuas qhov ntsuas yog 22/20 = 1.1. Qhov no txhais tau tias lub cev muaj zog yog overloaded los ntawm 10%
Yuav ua li cas hloov DC tam sim no rau AC tam sim no?
Lub hwj chim inverter, los yog inverter, yog apowerelectronic ntaus ntawv los yog circuitry uas hloov directcurrent (DC) mus rau alternating tam sim no (AC).Inputvoltage, tso zis voltage thiab zaus, thiab overallpower tuav nyob ntawm tus tsim ntawm lub specificdeviceor circuitry
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Yuav ua li cas koj hloov cov units me mus rau cov units loj?
Hloov cov chav me me mus rau cov chav loj loj dua chav tsev loj. Txhawm rau hloov los ntawm chav tsev loj dua mus rau ib qho me me, sib npaug. Txhawm rau hloov los ntawm chav tsev me mus rau qhov loj dua, faib
Yuav ua li cas koj xam tam sim no nrog voltage thiab kuj?
Ohms Txoj Cai thiab Lub Hwj Chim Kom Pom Qhov Voltage, (V) [V = I x R] V (volts) = I (amps) x R (Ω) Kom pom qhov tam sim no, (I) [I = V ÷ R] I ( amps) = V (volts) ÷ R (Ω) Nrhiav qhov Resistance, (R) [R = V ÷ I] R (Ω) = V (volts) ÷ I (amps) Nrhiav Lub Hwj Chim (P) [P = V x I] P (watts) = V (volts) x I (amps)
