In wareegyada DC, ah Capacitor Warshad waa sida jabiyaha oo kale oo sameeya wareeg furan. Capacitor disc Ceramic waa qayb ka mid ah qaybaha elegtarooniga ah ee ugu caansan, waana qayb lagu kaydiyo kharashka. Dhammaan kuwan waxaa sabab u ah qaab-dhismeedka capacitor, xitaa kan ugu fudud wuxuu yeelan doonaa laba korantada korantada oo ay kala soocaan kirishbooyada dielectric (oo ay ku jiraan hawada). Markaa ka dib markii la soo saaro, inta u dhaxaysa labada electrodes ee capacitor waxay samayn doonaan farqi suurtagal ah (voltage, sida iska caabin danab sare), mana noqon karto koronto loogu talagalay kirishtaankeeda dielectric ee dhexda ah. Laakiin waxay ku jiri kartaa oo keliya xaaladda aan la gaarin koronta burburka. Waynu ognahay, arin kastaa waa mid daharan, marka danabka ka gudba arrinka uu gaadho qiime cayiman, waxa uu noqon karaa conductive, danabkan waxa aanu u naqaannaa danabka burburay. Marka laga reebo, marka capacitor uu burburo, ma aha insulator. Si kastaba ha ahaatee, dugsiga dhexe, danab noocan oo kale ah looma arki karo wareegga, shaqada oo dhan waxay ku dhex jirtaa danab burburay, sidaas darteed capacitor waxaa lagu xukumi karaa insulator.
 　　
In wareegga AC, si kastaba ha ahaatee, sababta oo ah jihada hadda isbedel functional la wakhtiga, dallacaadda iyo soo daynta ee capacitor u baahan tahay waqti, ka dibna beerka koronto beddelmi karo u dhexeeya laba electrodes, iyo beerta this sidoo kale bedelay wakhtiga la xidhiidha functional. Dhab ahaantii, hadda wuxuu ku dhaafaa capacitor-ka kaliya habka beerta korontada. Dugsiga dhexe, xannibaadda tooska ah ee hadda jirta iyadoo la oggol yahay beddelka hadda inuu gudbo waxay muujisay macne isku mid ah.
