Kev hloov lub roj teeb qhov hluav taws xob cuam tshuam li cas tam sim no ? Qhov siab dua roj teeb voltage , qhov ntau dua qhov ntws ntawm tam sim no hauv Circuit Court. Qhov siab dua roj teeb voltage , lub teeb ci ntsa iab. Tshem cov hlau.
Ntxiv mus, qhov voltage puas cuam tshuam rau roj teeb lub neej?
Them nyob rau hauv siab hluav taws xob kuj cuam tshuam tus roj teeb lub neej . Koj ua tau saib cov lus hauv qab no. Nws qhia tias, roj teeb raug nqi siab hluav taws xob tseem ceeb raug kev txom nyem los ntawm kev poob hauv lub voj voog. Thaum twg roj teeb raug nqi siab hluav taws xob , lawv kub thiab cuam tshuam tus roj teeb muaj peev xwm mus tas li.
Kuj Paub, vim li cas lub roj teeb voltage txo? Yog hais tias peb txuas ib tug load hla lub roj teeb , cov hluav taws xob hla cov terminals poob. Qhov no poob hauv hluav taws xob yog tshwm sim los ntawm lub internal kuj ntawm lub roj teeb . Simplified rau qhov Circuit Court no, peb tuaj yeem hais tias qhov hluav taws xob poob nyob rau hauv ob qho tib si resistors yuav tsum ntxiv mus rau lub hluav taws xob ntawm qhov zoo tagnrho hluav taws xob qhov chaw.
Xav txog qhov no, qhov kev sib raug zoo ntawm qhov hluav taws xob tam sim no thiab qhov tsis kam yog dab tsi?
Cov kev sib raug zoo ntawm voltage , tam sim no, thiab kuj tau piav los ntawm Ohm txoj cai. Qhov kev sib npaug no, i = v / r, qhia peb tias qhov tam sim no , i, ntws los ntawm Circuit Court yog ncaj qha proportional rau lub hluav taws xob , v, thiab inversely proportional rau tus tsis kam , r.
Koj xav li cas txog kev nce qhov kev tawm tsam hauv Circuit Court yuav cuam tshuam rau qhov tam sim no hauv cov hlau?
Ohm txoj cai hais tias hluav taws xob tam sim no (I) ntws hauv ib Circuit Court yog proportional rau qhov voltage (V) thiab inversely proportional rau tus tsis kam (R). Yog li ntawd, yog hais tias tus voltage yog nce , cov tam sim no yuav nce muab cov tsis kam ntawm Circuit Court tsis hloov.

Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Dab tsi yog qhov txawv ntawm kev cuam tshuam kev cuam tshuam thiab kev cuam tshuam cuam tshuam?
Paub qhov txawv ntawm kev cuam tshuam kev tsim kho thiab kev cuam tshuam puas tsuaj. Kev tsim kev cuam tshuam tshwm sim thaum lub crests ntawm ob nthwv dej ntxiv ua ke. Kev cuam tshuam kev puas tsuaj tshwm sim thaum lub crest ntawm ib yoj raug txo los ntawm lub trough ntawm lwm tus
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Lub peev xwm hluav taws xob cuam tshuam li cas rau hluav taws xob teb?
Lub peev xwm hluav taws xob tsuas yog ua haujlwm ua haujlwm ib chav xwb kom txav nws los ntawm ib lub peev xwm mus rau lwm lub peev xwm hauv thaj chaw hluav taws xob. Qhov sib txawv ntawm ob qhov sib txawv equipotentials yog qhov muaj peev xwm sib txawv lossis qhov sib txawv voltage. Electric teb piav txog lub zog ntawm tus nqi
Koj ntsuas qhov voltage thiab tam sim no hauv hluav taws xob hluav taws xob li cas?
Ib qho cuab yeej hu ua ammeter yog siv los ntsuas tam sim no. Qee hom ammeter muaj lub pointer ntawm lub dial, tab sis feem ntau muaj cov duab digital. Txhawm rau ntsuas qhov tam sim no ntws los ntawm cov khoom siv hauv Circuit Court, koj yuav tsum txuas lub ammeter hauv series nrog nws
