Kev tiv thaiv yog qhov cuam tshuam rau kev khiav ntawm electrons hauv cov khoom. Thaum lub peev xwm sib txawv thoob plaws tus neeg xyuas pib txhawb kev ntws ntawm electrons, tsis kam ua rau nws poob siab. Tus nqi ntawm cov nqi ntws ntawm ob lub davhlau ya nyob twg yog qhov sib xyaw ntawm ob yam no.

Kuj paub, dab tsi yog qhov kev tiv thaiv hauv Circuit Court?

Kev tiv thaiv yog ib qho kev ntsuas ntawm qhov kev tawm tsam rau tam sim no ntws hauv hluav taws xob Circuit Court . Kev tiv thaiv ntsuas hauv ohms, cim los ntawm Greek tsab ntawv omega (Ω). Conductors: Cov khoom uas muaj tsawg heev tsis kam qhov twg electrons tuaj yeem txav tau yooj yim.

Ib tug kuj yuav nug, vim li cas thiaj xav tau kev tiv thaiv? Yog li ntawd, qee zaum nws yog ib qho tseem ceeb los ntxiv cov khoom hu ua resistors rau hauv hluav taws xob hluav taws xob kom txwv tsis pub cov hluav taws xob ntws thiab tiv thaiv cov khoom hauv Circuit Court. Kev tiv thaiv kuj yog qhov zoo vim nws muab peb txoj hauv kev los tiv thaiv peb tus kheej los ntawm kev phom sij ntawm hluav taws xob.

Nyob rau hauv txoj kev no, dab tsi yog kev tiv thaiv yooj yim txhais?

Resistance definition Resistance yog ib qho hluav taws xob ntau npaum li cas ntsuas cov cuab yeej lossis cov khoom siv txo cov hluav taws xob tam sim no los ntawm nws. Cov tsis kam ntsuas nyob rau hauv units ntawm ohms (Ω).

Dab tsi ua rau muaj kev tawm tsam hauv Circuit Court?

Ib qho hluav taws xob tam sim no ntws thaum electrons txav los ntawm ib tus neeg xyuas pib, xws li cov hlau hlau. Cov electrons txav tuaj yeem sib tsoo nrog cov ions hauv cov hlau. Qhov no ua rau nws nyuaj rau qhov tam sim no ntws, thiab ua rau tsis kam . Kev sib raug zoo ntawm tsis kam thiab hlau ntev yog proportional.
