Ohms Txoj Cai thiab Lub Zog

  1. Txhawm rau nrhiav qhov Voltage, (V) [V = I x R] V (volts) = I (amps) x R (Ω)
  2. Yuav nrhiav tau Tam sim no , (I) [I = V ÷ R] I (amps) = V (volts) ÷ R (Ω)
  3. Txhawm rau nrhiav qhov Resistance, (R) [R = V ÷ I] R (Ω) = V (volts) ÷ I (amps)
  4. 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.
