Basic hluav taws xob : Hluav taws xob yog qhov ntws ntawm electrons los ntawm ib qho chaw mus rau lwm qhov. Cov hluav taws xob tuaj yeem ntws los ntawm txhua yam khoom siv, tab sis ua tau yooj yim dua hauv qee qhov ntau dua li lwm tus. Semi-conductors: electron tuaj yeem ua kom ntws raws li qee qhov xwm txheej.
Tsis tas li ntawd, cov kev cai yooj yim ntawm hluav taws xob yog dab tsi?
Peb tau teeb tsa cov ntsiab cai no ua peb cov cai yooj yim : Txoj cai 1 – Hluav taws xob yuav ib txwm xav kom ntws los ntawm qhov hluav taws xob siab dua mus rau qhov qis dua. Txoj cai 2 – Hluav taws xob ib txwm muaj cov haujlwm uas yuav tsum tau ua. Txoj cai 3 – Hluav taws xob ib txwm xav tau txoj kev mus ncig.
Tom qab, lo lus nug yog, dab tsi yog tam sim no thiab voltage? 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).
Kev sib raug zoo, cov nqe lus ntawm hluav taws xob yog dab tsi?
Cov ntsiab lus hluav taws xob yooj yim
| Hloov tam sim no (AC) | Hluav taws xob tam sim no uas thim rov qab cov lus qhia ntawm lub sijhawm tsis tu ncua. |
|---|---|
| Hluav taws xob | Kev khiav ntawm electrons. |
| Hluav taws xob | Ib tug tsis zoo nqi particle uas orbits lub nucleus ntawm ib tug atom. Kev khiav ntawm electrons tsim hluav taws xob. |
| Zog | Muaj peev xwm ua haujlwm. Zog = Hwj chim x Sijhawm |
Peb txoj cai ntawm hluav taws xob yog dab tsi?
Raws li tib hom kev sim xws li qhov koj tau ua, cov kws tshawb fawb muaj peev xwm tsim tau peb txoj cai ntawm cov nqi hluav taws xob:
- Cov nqi sib txawv sib txawv.
- Zoo li cov nqi sib tw.
- Cov khoom them nqi nyiam cov khoom nruab nrab.
