Cov tam sim no dhau ntawm 5 - ohm resistor yog 2.4 amper.
Hais txog qhov no, dab tsi yog tam sim no los ntawm 5 ohm tsis kam?
Siv superposition theorem, peb tau txais: Thaum tsuas yog sab laug sab 10 V qhov chaw nyob ntawd, yog luv luv hla sab xis 10 V qhov chaw, yog li Tam sim no los ntawm 5 ohm resistor yog zero. Nws zoo ib yam thaum tsuas yog sab xis 10 V qhov chaw ua yeeb yam. Yog li tag nrho tam sim no hla 5 ohm resistor yog zero.
Dab tsi yog qhov tam sim no thaum qhov tsis kam yog 5 ohms thiab qhov hluav taws xob yog 10 volts? Kev piav qhia: 10 / 5 = 2 Tam sim no = 2 amperes.
Kuj kom paub, dab tsi yog qhov txawv ntawm qhov resistor ntawm 5.0 uas yog tam sim no ntawm 5.0 A?

Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
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
Dab tsi yog qhov kev ua yuam kev hauv kev sim nrog cov hluav taws xob tam sim no?
Cov peev txheej ntawm kev ua yuam kev suav nrog cov cuab yeej, ib puag ncig, txheej txheem, thiab tib neeg. Tag nrho cov kev ua yuam kev no tuaj yeem ua tsis tau lossis ua haujlwm nyob ntawm seb lawv cuam tshuam li cas. Instrumental yuam kev tshwm sim thaum cov cuab yeej siv tsis raug, xws li qhov sib npaug uas tsis ua haujlwm (SF Fig
Koj pom dab tsi tam sim no dhau los ntawm txhua tus resistor?
Txij li thaum txhua tus resistor hauv Circuit Court muaj tag nrho cov voltage, cov dej ntws los ntawm tus kheej resistors yog I1 = VR1 I 1 = VR 1, I2 = VR2 I 2 = VR 2, thiab I3 = VR3 I 3 = VR 3. Kev txuag nqi txhais tau hais tias tag nrho tam sim no kuv tsim los ntawm qhov chaw yog qhov suav ntawm cov tam sim no: I = I1 + I2 + I3
Qhov twg yog qhov cua sov los ntawm qhov uas ua rau qhov tam sim no convection hauv lub mantle?
