Hluav taws xob yog qhov tsis zoo them, thiab yog li txaus siab rau qhov zoo kawg ntawm lub roj teeb thiab rov qab los ntawm qhov kawg kawg. Yog li thaum lub roj teeb yog hooked mus rau ib yam dab tsi uas cia lub electrons ntws ntawm nws, lawv ntws los ntawm qhov tsis zoo mus rau qhov zoo.
Yog li ntawd, electron ntws li cas?
Electron ntws yog qhov peb xav tias yog hluav taws xob. AC yog thaum lub electrons ntws nyob rau hauv ob txoj kev, los ntawm qhov zoo mus rau qhov tsis zoo davhlau ya nyob twg thiab los ntawm qhov tsis zoo mus rau qhov zoo davhlau ya nyob twg, 'alternating' ntawm ob qho kev taw qhia. electron ntws .)
Ib yam li ntawd, hluav taws xob yog dab tsi thiab nws ntws li cas? Hluav taws xob yog a ntws ntawm me me particles hu ua electrons uas tuaj yeem taug kev los ntawm cov xov hlau. Qhov no ntws feem ntau hu ua ' hluav taws xob tam sim no'. Ib yam li dej, uas ua tau xwb ntws nram toj, ib hluav taws xob currentcan xwb ntws yog tias muaj ib yam dab tsi los muab nws 'push'.
Yog li ntawd, yuav ua li cas lub electron ntws nyob rau hauv ib tug conductor?
Thaum muab cov khoom uas muaj nqi zoo nyob ze ntawm a conductor electrons yog attracted tus kwv. Metalscontain dawb txav delocalized electrons . Thaum siv hluav taws xob hluav taws xob, ib qho hluav taws xob hauv cov hlau ua rau lub zog ntawm qhov electrons , ua rau lawv hloov ntawm ib kawg mus rau lwm qhov kawg ntawm lub tus thawj coj.
Cov khoom siv hluav taws xob li cas?
Lub zog kom tau txais electrons txav mus rau hauv txoj kev tsis sib haum xeeb los ntawm lub roj teeb lossis lub tshuab hluav taws xob. Thaum lub roj teeb teeb tsa electrons lawv txhua tus txav mus rau tib txoj kev nyob rau tib lub sijhawm - lub roj teeb twj tso kua mis electrons los ntawm cov kab hluav taws xob los ntawm qhov tsis zoo mus rau qhov zoo.

Hom hluav taws xob hluav taws xob muaj nyob hauv tsheb li cas?
Lub tshuab hluav taws xob ntawm lub tsheb yog lub kaw lus kaw nrog lub zog ywj pheej ntawm lub roj teeb. Nws ua hauj lwm ntawm ib feem me me ntawm lub hwj chim ntawm ib tsev neeg circuit
Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
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
