Ohm txoj cai yog ib tug qauv siv los xam cov kev sib raug zoo ntawm voltage, tam sim no thiab kuj nyob rau hauv ib tug hluav taws xob Circuit Court. Rau cov tub ntxhais kawm ntawm electronics, Ohm txoj cai (E = IR) yog Raws li qhov tseem ceeb ntawm Einstein's Relativity equation (E = mc²) yog rau physicists.

Ib yam li ib tug yuav nug, Ohm txoj cai piav qhia yog dab tsi?

Ohm txoj cai . [awm] A txoj cai hais txog qhov sib txawv ntawm qhov sib txawv ntawm ob lub ntsiab lus, cov hluav taws xob tam sim no ntws nruab nrab ntawm lawv, thiab qhov tsis kam ntawm txoj kev ntawm qhov tam sim no. Mathematicically, cov txoj cai hais tias V = IR, qhov twg V yog qhov sib txawv voltage, kuv yog tam sim no nyob rau hauv amperes, thiab R yog qhov tsis kam nyob rau hauv ohms ua.

Tsis tas li ntawd, Ohm txoj cai nrog piv txwv yog dab tsi? Ib lub tswv yim piv txwv Lub roj teeb yog 12 volt roj teeb, thiab qhov kev tiv thaiv ntawm cov resistor yog 600 Ohm . Tam sim no npaum li cas los ntawm Circuit Court? Yog li tam sim no hauv Circuit Court yog 20 mA. Yog tias koj tsis nyiam suav cov khoom koj tus kheej, kos tawm lub tshuab xam zauv no rau Ohm txoj cai.

Raws li txoj cai, 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.

Vim li cas Ohm txoj cai tseem ceeb?

Ohm txoj cai yog tseem ceeb heev tseem ceeb piav qhia txog hluav taws xob circuits vim hais tias nws cuam tshuam qhov voltage rau tam sim no, nrog rau tus nqi tsis kam ua kom muaj kev sib raug zoo ntawm ob.
