Sab laug rau lawv tus kheej, ob lub tsub hluav taws xob ntawm tib lub npe xav tsis muaj dab tsi ua nrog ib leeg. Lawv ya sai li sai tau. Yog li, yog tias cov khoom raug yuam kom txav mus rau ib leeg (thiab qhov no tshwm sim, piv txwv li, thaum sib sau ua ke), lawv tawm tsam qhov no hauv txhua txoj hauv kev, thiab txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm yuav tsum tau siv.
Nyob rau hauv lub xeev zoo li qub, lub zog no tsis siv thiab tsis tuaj yeem ploj mus. Nws yog khaws cia raws li hluav taws xob teb - ib hom kev nro nyob rau hauv qhov chaw nruab nrab ntawm cov nqi them - kom txog thaum cov concentration ntawm cov nqi txo, thiab lawv rov muaj peev xwm txav mus los dawb.
Nyob rau hauv rooj plaub no, tus nqi siv lub zog ntawm hluav taws xobteb kom tau acceleration ntawm nws txoj kev.
Ib lub capacitor yog cov khoom siv hluav taws xob hluav taws xob tshwj xeeb tsim los khaws cov hluav taws xob.
Lub zog ntawm lub zog hluav taws xob ntawm lub capacitor yog lub hauv paus ntawm nws siv hauv ntau cov khoom siv hluav taws xob thiab hluav taws xob.
Yooj yim logic dictates tias lub capacitor them rau qhov voltage ntawm V yuav xav tau QV joules ntawm lub zog kom ncav cuag lub xeev tshiab, thiab tus nqi no yog lub zog ntawm lub zog hluav taws xob ntawm lub capacitor, khaws cia hauv nws thiab npaj rau siv.
Hmoov tsis zoo, kev xav tsis zoo ntawm no. Tsuas yog vim tias koj hnov zoo tom qab haus npias, tsis tau txhais hais tias koj yuav hnov zoo li ob zaug tom qab haus qhov thib ob.
Qhov tseeb, raws li kev tsub nqi, lawv tawm tsam nws ntau dua thiab hnyav dua. Pom tseeb, ntawm no peb tab tom cuam tshuam nrog cov txheej txheem tsis-linear.
Cia saib yuav ua li cas lub zog ntawm lub zog hluav taws xob ntawm lub capacitor txiav txim siab raws li kev sim yooj yim.
Nws paub tias tam sim no txhais tau tias yog qhov nrawm uas tus nqi txav mus. Yog li ntawd, yog tias koj txuas lub capacitor mus rau qhov chaw ntawm stabilized tam sim no, tus nqi Q yuav sau rau ntawm daim hlau ntawm tus nqi tas li.
xav tias peb muab lub capacitor uas tsis tau them nyiaj thiab txuas rau lub hwj chim uas muab cov nqi them tas li I.
Voltage ntawm lub capacitor pib ntawm xoom thiab ncelinearly kom txog thaum lub capacitor tau them tag nrho. Tom qab ntawd nws nres. Wb hu tus nqi no qhov siab tshaj voltage V.
Qhov nruab nrab qhov hluav taws xob hla lub capacitor thaum them nyiaj yog (V / 2), thiab lub zog nruab nrab, raws li, yog I (V / 2). Lub capacitor raug them hauv lub sijhawm T vib nas this, yog li lub zog ntawm lub zog hluav taws xob ntawm lub capacitor khaws cia hauv cov txheej txheem ntawm kev them nyiaj yog TI (V/2).
W=1/2QV=1/2CV
Txawm hais tias muaj ntau qhov ntau thiab tsawg, cov khoom siv capacitor tsis muaj ntau haiv neeg.
Feem ntau ntawm lawv muaj ob daim phiaj sib luag sib cais los ntawm dielectric. Qee zaum, kom txuag tau qhov chaw, cov qhaub cij no tau dov zoo li yob. Thiab qee zaum lawv muaj ob peb txheej, txuas rau hauv ib txoj kev.
Xaiv lub peev xwm ntawm lub capacitor uas muaj ob daim hlau, nrog rau lub cev paub qhov ntev, feem ntau tsis yooj yim, nrog rau kev suav cov txiaj ntsig tau tshwm sim thaum cov capacitors txuas nrog hauv cov koob lossis sib npaug.
