Cov hluav taws xob teb ntawm lub nplhaib ntawm tus nqi ntawm lub axis ntawm lub nplhaib tuaj yeem pom los ntawm superposing tus nqi taw tes teb ntawm infinitesmal nqi ntsiab. Lub nplhaib teb tuaj yeem siv los ua ib qho khoom siv los suav cov hluav taws xob teb ntawm tus nqi them disc.
Yog li ntawd, qhov loj ntawm qhov hluav taws xob yog dab tsi?
tus qhov loj ntawm qhov hluav taws xob (E) tsim los ntawm tus nqi taw tes nrog tus nqi ntawm qhov loj Q, ntawm qhov taw tes qhov deb r deb ntawm tus nqi taw tes, yog muab los ntawm kab zauv E = kQ / r2, qhov twg k yog qhov tsis tu ncua nrog tus nqi ntawm 8.99 x 109 N m2/C2.
Qhov thib ob, lub zog hluav taws xob yog dab tsi? Ib hluav taws xob yog exerted ntawm ob yam khoom uas them. Cov khoom nrog tib tus nqi, ob qho tib si zoo thiab ob qho tib si tsis zoo, yuav tawm tsam ib leeg, thiab cov khoom nrog cov nqi sib txawv, ib qho zoo thiab ib qho tsis zoo, yuav sib nyiam.
Ib yam li ntawd, tib neeg nug, chav tsev hluav taws xob yog dab tsi?
The SI units ntawm hluav taws xob teb yog newtons per coulomb (N/C), los yog volts per meter (V/m).
Lub tshuab hluav taws xob siv hluav taws xob yog dab tsi?
Cov hluav taws xob siv zog ntawm ib qho taw tes yog lub zog uas tau ntsib los ntawm ib chav tsev zoo nqi tso rau ntawm qhov chaw ntawd. Fais Field Intensity yog vector kom muaj nuj nqis. Nws yog denoted los ntawm 'E'. Formula : Hluav taws xob Field = F/q. Unit of E is NC-1 lub Vm-1.

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
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 hloov hluav taws xob ua hluav taws xob li cas?
Tig Hluav Taws Xob rau Hluav Taws Xob (BioLite CampStove) Yog tias koj muaj cua sov ntau, ces koj tuaj yeem ua li cas fais fab nroj tsuag ua: siv cov cua sov los ua kom muaj zog, thiab siv lub steamto tig lub turbine. Lub turbine tuaj yeem tsav lub tshuab hluav taws xob, uas tsim hluav taws xob
Kev sib raug zoo ntawm hluav taws xob thiab hluav taws xob teb yog dab tsi?
Electric teb yog txhais raws li lub zog hluav taws xob ib chav tsev nqi. Cov kev taw qhia ntawm lub teb yog coj mus rau qhov kev taw qhia ntawm lub zog nws yuav ua rau ib tug zoo kuaj nqi. Cov hluav taws xob hluav taws xob yog radially sab nraud los ntawm tus nqi zoo thiab radially mus rau qhov tsis zoo ntawm tus nqi
