Qhov hluav taws xob yog lub siab los ntawm cov hluav taws xob hluav taws xob hluav taws xob lub zog uas thawb cov hluav taws xob hluav taws xob ( tam sim no ) los ntawm ib tug conducting voj, enabling lawv ua haujlwm xws li illuminating lub teeb. Hauv luv luv, hluav taws xob = siab, thiab nws yog ntsuas nyob rau hauv volts (V). Tam sim no rov qab mus rau lub zog.

Ib yam li ntawd, nws tau nug, tam sim no thiab voltage cuam tshuam li cas?

Cov tam sim no yog ncaj qha proportional rau lub hluav taws xob thiab inversely proportional rau qhov tsis kam. Qhov no txhais tau hais tias nce lub hluav taws xob yuav ua rau tam sim no kom nce, thaum nce qhov tsis kam yuav ua rau lub tam sim no txo.

Dab tsi yog 3 hom ntawm Ohm txoj cai? 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.

Khaws qhov no hauv kev xav, dab tsi yog qhov voltage hauv cov lus yooj yim?

Qhov hluav taws xob yog dab tsi ua rau cov nqi hluav taws xob txav mus. Nws yog 'thawj' uas ua rau cov nqi txav mus rau hauv ib lub xaim lossis lwm yam khoom siv hluav taws xob. Qhov hluav taws xob tseem hu ua, hauv qee qhov xwm txheej, electromotive force (EMF). Qhov hluav taws xob yog qhov hluav taws xob muaj peev xwm sib txawv, qhov sib txawv ntawm hluav taws xob muaj peev xwm ntawm ob qhov chaw.

Vcc voltage yog dab tsi?

Vcc . Ib qho khoom siv hluav taws xob uas hais txog hluav taws xob los ntawm lub hwj huam mov txuas nrog lub "collector" davhlau ya nyob twg ntawm ib tug bipolar transistor. Hauv NPN bipolar (BJT) transistor, nws yuav yog +Vcc ua, thaum nyob hauv PNP transistor, nws yuav yog -Vcc ua. Ob tsab ntawv (cc) xa mus rau lub hwj chim mov voltages.
