Lub roj teeb puas muaj tam sim no?

‌The battery will generate current when connected to an external circuit, but when the circuit is not connected, the internal state is in equilibrium and there is no current on a macroscopic scale. ‌ The generation of current depends on the chemical reaction inside the battery and the closure of the external circuit, and the direction is opposite inside the battery and in the external circuit.

Roj teeb tam sim no lub ntsiab cai

Kev Siv Hluav Taws Xob Lub Zog Hluav Taws Xob: Cov Roj Teeb Hloov Hluav Taws Xob (xws li cov hluav taws xob tsis zoo los ntawm cov hluav taws xob sib txawv ntawm cov khoom siv hluav taws xob sab hauv (uas yog cov khoom sib txawv
Cov kev taw qhia tam sim no:
Sab Nraud Circuit Court: Cov kev taw qhia tam sim no txhais tau tias yog kev coj ua kom zoo (zoo electrode), uas yog rov qab rau qhov tseeb kev coj ntawm electron now {}}
Sab hauv Circuit Court: Tsis muaj hluav taws xob yuam kev tsav tau zoo los ntawm cov kev taw qhia zoo rau hluav taws xob →
Cov xwm txheej rau lub neej ntawm hluav taws xob tam sim no
Thaum lub Circuit Court tsis txuas nrog: vim qhov sib npaug ntawm cov hluav taws xob hauv lub roj teeb, tsis muaj qhov tam sim no ntawm lub teeb liab ntawm macroscopic, thiab tsuas yog microscopic tsub txav {}}
Thaum lub Circuit Court txuas ntxiv: Kev tswj cov tshuaj tiv thaiv cov tshuaj txuas ntxiv, kev ua kom muaj peev xwm ua qhov sib txawv, tsav tsheb kev txav ntawm cov nqi tas li los ua qhov tam sim no {}}
Cov hom thiab cov yam ntxwv tam sim no

Lub roj teeb tawm yog ncaj qha tam sim no (DC), thiab cov kev taw qhia ntawm tam sim no yog qhov tsis txaus ntseeg ntawm cov tshuaj lom neeg ntawm cov tshuaj tiv thaiv ntawm cov tshuaj lom neeg tam sim no nyob ntawm:

Sab hauv kev tiv thaiv: qhov me dua sab hauv kev tawm tsam, qhov loj dua qhov tso tawm tam sim no .
Load: Cov kev tawm tsam ntawm cov hluav taws xob sab nraud cuam tshuam rau kev siv hluav taws xob tam sim no (ua raws OHM txoj cai).
