Thaum a dielectric cov khoom siv tau qhia nruab nrab ntawm daim phiaj Thiab thaum a dielectric cov khoom yog muab tso rau nruab nrab ntawm daim phiaj ntawm parallel phaj capacitor ces vim polarization ntawm nqi ntawm ob sab ntawm lub dielectric , nws tsim ib qho hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite rau ntawm lub teb vim
Ib yam li ntawd, thaum cov khoom siv dielectric ntxig rau ntawm daim hlau ntawm lub capacitor nws nce nws?
Parallel Phaj nrog Dielectric Cov capacitance ntawm ib txheej ntawm them parallel daim hlau yog nce los ntawm kev ntxig ntawm a cov khoom siv dielectric . Cov capacitance yog inversely proportional rau hluav taws xob teb nruab nrab ntawm daim phiaj , thiab lub xub ntiag ntawm dielectric txo cov hluav taws xob zoo.
Kuj Paub, thaum lub slab ntawm dielectric nruab nrab muab tso rau ntawm daim hlau? Thaum a dielectric yog muab tso rau nruab nrab raug them daim hlau , polarization ntawm lub nruab nrab ua ib qho hluav taws xob teb opposing lub teb ntawm cov nqi ntawm cov phaj.
Tsis tas li ntawd nug, thaum lub dielectric slab khaws cia ntawm ob daim hlau ntawm lub phaj parallel capacitor ces Polarization yog sib npaug?
Thaum twg dielectric muab tso rau nruab nrab tus ob daim hlau ntawm parallel phaj capacitor , nws yog polarized los ntawm hluav taws xob teb tam sim no. Tus nqi ntawm qhov ntom ntom yog suav tias yog σp thiab - σp. Thaum lub dielectric muab tso rau tag nrho nruab nrab tus ob daim hlau ntawm capacitor ces nws yog dielectric tas li nce los ntawm nws lub tshuab nqus tsev nqi.
Yuav ua li cas tshwm sim thaum lub dielectric raug tshem tawm ntawm lub capacitor?
Thaum lub dielectric raug tshem tawm , tus nqi ntawm daim hlau, Q, tsis hloov. Cov capacitance C txo qis, yog li lub zog yuav tsum nce. Yog cov paib ntawm cov capacitor txuas nrog lub roj teeb zoo tagnrho, ces qhov voltage, tsis yog tus nqi, yuav nyob twj ywm, thiab lub zog khaws cia yuav txo qis.

Yuav ua li cas tshwm sim rau tam sim no nyob rau hauv ib tug parallel circuits thaum ntxiv qhov muag teev?
Raws li ntau qhov muag tau ntxiv, qhov tam sim no nce. Raws li ntau resistors ntxiv nyob rau hauv parallel, tag nrho tam sim no lub zog nce. Yog li ntawd, tag nrho cov tsis kam ntawm Circuit Court yuav tsum tau txo. Qhov tam sim no nyob rau hauv txhua lub teeb yog tib yam vim hais tias tag nrho cov qhov muag teev glowed nrog tib brightness
Thaum cov khoom siv dielectric ntxig rau ntawm daim hlau ntawm lub capacitor nws nce nws?
Thaum lub dielectric tag nrho muab tso rau ntawm ob daim hlau ntawm capacitor ces nws yog dielectric tas li nce los ntawm nws lub tshuab nqus tsev nqi. Yog li, thiab, yog qhov kev tso cai ntawm cov khoom
Yuav ua li cas tshwm sim thaum ib tug tam sim no nqa coil muab tso rau hauv ib tug magnetic teb?
Yog tias tus neeg nqa khoom nqa tam sim no tau muab tso rau hauv qhov chaw sib nqus, nws ntsib lub zog Lorentz (tshwj tsis yog lub kaum sab xis ntawm qhov ntws ntawm tam sim no thiab cov kab hlau nplaum yog 0 °)
Yuav ua li cas tshwm sim thaum dilute sulfuric acid yog nchuav rau ntawm zinc phaj?
Thaum dilute Sulfuric acid yog nchuav rau ntawm ib lub zincplate, Zinc Sulphate yog tsim nrog Hydrogen gas.Peb tuaj yeem kuaj cov roj hydrogen los ntawm kev noj cov khoom siv hluav taws xob ze ze, thiab cov roj yuav ignite nrog lub suab nrov
Yuav ua li cas tshwm sim thaum koj muab cov khoom them nqi ze ntawm Electroscope thiab vim li cas?
Hauv cov txheej txheem induction ntawm kev them nyiaj, ib qho khoom them raug coj los ze rau tab sis tsis kov lub electroscope. Qhov no tau piav qhia los ntawm cov kev them nqi zoo li lub hauv paus ntsiab lus. Lub zais pa uas tsis zoo tiv thaiv cov hluav taws xob tsis zoo, yog li yuam kom lawv txav mus los
