Hluav taws xob tam sim no a ntws ntawm hluav taws xob nqi (feem ntau hauv daim ntawv ntawm electrons) dhau ib yam khoom. Cov khoom los yog tus neeg xyuas pib uas ib hluav taws xob tam sim no ntws los ntawm yog feem ntau hlau hlau, txawm tias tam sim no tau kuj ntws los ntawm qee cov roj, kua, thiab lwm yam khoom siv.
Tib neeg kuj nug, ua li cas cov hluav taws xob tam sim no ntws los ntawm ib lub voj voog?
Kev taw qhia ntawm ib hluav taws xob tam sim no yog los ntawm convention cov kev taw qhia hauv uas tus nqi zoo yuav txav mus. Yog li ntawd, lub tam sim no hauv sab nraud Circuit Court yog qhia deb los ntawm qhov zoo davhlau ya nyob twg thiab mus rau qhov tsis zoo davhlau ya nyob twg ntawm lub roj teeb. Electrons yeej yuav txav mus dhau cov kab hauv txoj kev ntxeev siab.
Tsis tas li ntawd, puas hluav taws xob tam sim no ntws los ntawm qhov tsis zoo mus rau qhov zoo? Tsiv Hauv Ib Txoj Kev The tam sim no nyob rau hauv DC circuits yog tsiv mus nyob rau hauv ib qho kev coj. Yog li txawm tias electrons yuav ntws los ntawm qhov tsis zoo mus rau qhov zoo , los ntawm convention (pom zoo), physicists hais txog cov pa tam sim no as a ntws los ntawm qhov muaj peev xwm / voltage ( zoo ) mus rau qhov tsis muaj peev xwm / voltage ( tsis zoo ).
Hais txog qhov no, tam sim no ntws li cas?
Tam sim no yog ntws ntawm electrons, tab sis tam sim no thiab electron ntws nyob rau hauv qhov opposite direction. Tam sim no ntws los ntawm qhov zoo rau qhov tsis zoo thiab electron ntws los ntawm qhov tsis zoo mus rau qhov zoo. Tam sim no yog txiav txim los ntawm tus naj npawb ntawm cov electrons dhau los ntawm ib ntu ntawm tus neeg xyuas pib hauv ib thib ob.
Tam sim no thiab voltage yog dab tsi?
Tam sim no yog tus nqi uas tus nqi hluav taws xob ntws dhau los ntawm ib qho chaw hauv ib lub voj voog. Hauv lwm lo lus, tam sim no yog tus nqi ntws ntawm cov nqi hluav taws xob. Qhov hluav taws xob , tseem hu ua electromotive force, yog qhov sib txawv ntawm tus nqi ntawm ob lub ntsiab lus hauv qhov hluav taws xob. Tam sim no yog cov nyhuv ( hluav taws xob yog vim li cas).

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
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
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
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
Puas yog hluav taws xob tam sim no ntws los ntawm qhov tsis zoo mus rau qhov zoo?
Cov kws tshaj lij hluav taws xob hais tias, hauv hluav taws xob hluav taws xob, hluav taws xob ntws mus rau ib qho kev taw qhia: tawm ntawm qhov zoo ntawm lub roj teeb thiab rov qab mus rau qhov tsis zoo. Cov kws tshaj lij hauv hluav taws xob hais tias hluav taws xob ntws mus rau lwm qhov kev taw qhia: tawm ntawm qhov tsis zoo ntawm lub roj teeb thiab rov qab mus rau qhov zoo davhlau ya nyob twg
