Ohms Txoj Cai thiab Lub Zog
- Txhawm rau nrhiav qhov Voltage, (V) [V = I x R] V (volts) = I (amps) x R (Ω)
- Yuav nrhiav tau Tam sim no , (I) [I = V ÷ R] I (amps) = V (volts) ÷ R (Ω)
- Txhawm rau nrhiav qhov Resistance, (R) [R = V ÷ I] R (Ω) = V (volts) ÷ I (amps)
- Kom pom lub hwj chim (P) [P = V x I] P (watts) = V (volts) x I (amps)
Ntawm no, koj yuav ua li cas pom qhov tam sim no ntws los ntawm tus resistor?
Rau xam lub zog poob hla ib tug resistor , nco ntsoov: Ohm Txoj Cai (V = I * R) yog koj tus phooj ywg. Nrhiav tus tam sim no ntws los ntawm ib tug resistor , ces multiply tam sim no nyob rau hauv amps los ntawm tsis kam nyob rau hauv ohms kom pom qhov voltage poob hauv volts.
Kuj Paub, 3 daim ntawv ntawm Ohm txoj cai yog dab tsi? Ohm txoj cai
- Hloov tam sim no.
- Capacitance.
- Direct tam sim no.
- Hluav taws xob tam sim no.
- Hluav taws xob muaj peev xwm.
- Electromotive quab yuam.
- Impedance.
- Inductance.
Ntawm no, dab tsi yog tus qauv rau amps?
Cov formula rau Amps yog Watts faib los ntawm Volts. Txhawm rau siv daim ntawv qhia, npog A nrog koj tus ntiv tes thiab siv daim ntawv qhia ntxiv xam ntawm W faib los ntawm V. Siv peb cov qauv vaj huam sib luag cov ntaub ntawv, 60 watts muab faib los ntawm 12 volts sib npaug 5 cov amps.
Dab tsi yog qhov voltage hauv Circuit Court?
Peb txhais hluav taws xob raws li qhov muaj peev xwm zog ntawm ob lub ntsiab lus ntawm a Circuit Court . Ib lub ntsiab lus muaj nqi ntau dua lwm qhov. Qhov sib txawv ntawm tus nqi ntawm ob lub ntsiab lus yog hu ua hluav taws xob.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Koj yuav suav li cas hnub nyoog sib tam?
Cov mis rau kev suav hnub nyoog ntawm ib txheej los ntawm txoj kev suav no yog: Tsis muaj hnub nyoog nyob rau hauv xyoo (A) = lub sij hawm dhau mus txij li thaum tsim cov txheej txheem tshiab tshaj plaws (R) ntxiv rau (tus naj npawb ntawm txheej (N) pw saum txheej nyob rau hauv nqe lus nug multiplied los ntawm lub sij hawm (D) ntawm lub depositional voj voog)
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 tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
