Zoo, ntawm no peb nyob thiab tau poob mus rau qhov thib ob series txog hluav taws xob. Nyob rau hauv thawj qhov chaw, muaj ib tug quote uas tsa kev tsis ntseeg ntawm ntau. Tshwj xeeb tshaj yog rau cov tsis ntseeg, peb hais ncaj qha. Nws yog qhov tseeb tsis tsim nyog tso dag txog lub peev xwm ntawm lub hlwb ntawm tus kws tshawb fawb ntawm qhov loj no. Tab sis hais txog kev hwm rau qhov tseeb tias nws tsis kam hais tawm yog qhov tsim nyog. Tom qab tag nrho, koj tsis hnov qhov no txhua hnub los ntawm dinosaurs ntawm kev tshawb fawb uas sau phau ntawv rau peb.

Los ntawm txoj kev, hais txog cov phau ntawv. Hauv thawj ntu, muaj ntau qhov kev sim ntawm electrostatics, tab sis ob peb tau mloog zoo rau qhov tsis sib xws. Hauv ib phau ntawv physics, koj tuaj yeem pom ib qho piv txwv ntawm qhov hluav taws xob zoo li cas tshwm sim thaum koj rub ib daim ntaub ntaub ntawm ebonite. Nws yog sau cia raws li nram no: electrons ntws los ntawm cov ntaub wool no mus rau ebonite. Ib qho dhau ntawm cov electrons tsub lub ebonite tsis zoo. Txhua yam zoo li pom tseeb thiab pom tseeb. Tab sis dab tsi txog qhov tseeb tias ebonite yog dielectric? Hauv ob peb nplooj ntawv tom qab, hauv tib phau ntawv, peb kawm tias cov electrons hauv atoms ntawm dielectrics tau ruaj khov nyob rau hauv qhov chaw thiab txav tsis tau. Yuav ua li cas peb soj ntsuam thaum peb rub cov yeeb nkab tsis zoo no nrog cov ntaub plaub? Qhov kev tsis sib haum xeeb no tau lees paub los ntawm cov kev paub dhau los ntawm qhov chaw ntawm tus nqi hauv lub capacitor, uas peb tau pom hauv cov yeeb yaj kiab kawg (thawj ntu ntawm cov koob no tsuas yog hauv qab).
