Cov zog ntawm hluav taws xob teb nyob ntawm tus nqi them, tsis nyob ntawm tus nqi kuaj. Ib kab tangent rau a teb kab qhia kev taw qhia ntawm cov hluav taws xob teb ntawm qhov ntawd. Qhov twg kab kab nyob ze ua ke, cov hluav taws xob teb muaj zog tshaj qhov lawv nyob deb deb.

Ntawm no, dab tsi yog tus qauv rau lub zog hluav taws xob?

SI unit of hluav taws xob teb zog yog newtons per coulomb (N/C) los yog volts per meter (V/m). Lub zog tau ntsib los ntawm qhov kev xeem me me heev q muab tso rau hauv a teb E hauv lub tshuab nqus tsev yog muab los ntawm E = F / q, qhov twg F yog qhov kev quab yuam.

Ib yam li ntawd, kev sib raug zoo ntawm lub zog hluav taws xob thiab hluav taws xob yog dab tsi? Hluav taws xob teb yog txhais raws li tus hluav taws xob ib unit nqi. Kev taw qhia ntawm lub teb yog coj los ua tus coj zog nws yuav siv sij hawm rau ib tug zoo kuaj nqi. Cov hluav taws xob teb yog radially sab nraud los ntawm tus nqi zoo thiab radially nyob rau hauv mus rau tus nqi tsis zoo.

Qhov thib ob, qhov chaw hluav taws xob muaj zog tshaj plaws?

Kev taw qhia ntawm lub teb kab ntawm ib tug taw tes yog cov kev taw qhia ntawm lub teb ntawm qhov ntawd. Tus txheeb ze magnitude ntawm lub hluav taws xob teb yog proportional rau qhov ceev ntawm lub teb kab. Qhov twg teb kab nyob ze ua ke teb muaj zog tshaj ; qhov twg teb kab sib nrug deb teb yog qaug zog.

Lub zog ntawm hluav taws xob yog dab tsi?

Electric teb zog yog ib tug quantitative qhia ntawm qhov kev siv ntawm ib hluav taws xob teb ntawm qhov chaw tshwj xeeb. Tus qauv ntsuas yog volt ib 'meter' (v / m lossis v · m -1). Cov teb zog ntawm ib qho kev ncua deb ntawm ib yam khoom yog ncaj qha proportional rau tus hluav taws xob them, hauv coulombs, ntawm qhov khoom ntawd.
