A capacitor contains electrodes, which consist of two metal plates or metal films that face each other. An insulator (or a dielectric substance), which can be made of various materials, is placed between the electrodes. (In the diagram, air acts as an insulator.)
When voltage is applied to both electrodes by connecting the positive and negative terminals of a battery, the facing electrodes will become positively and negatively charged.
The electric charges will remain even after the power source has been disconnected, as the capacitor has a charging effect. When the electrodes of a charged capacitor are shorted, there will be a momentary flow of current, and the stored charge will become neutralized and disappear. Thus, the capacitor is discharged.

Kondenseta ina elektroni, ambazo zina sahani mbili za chuma au filamu za chuma zinazokabiliana. Kiunganishi (au dutu ya dielectric), ambayo inaweza kufanywa ya vifaa mbalimbali, ni kuwekwa kati ya electrodes. (Katika mchoro huo, hewa hutenda kama kiunganishi.) Wakati voltage ni kutumika kwa electrodes zote mbili kwa kuunganisha positives na negatives ya betri, electrode inakabiliwa itakuwa chanya na negatively charged. Mashtaka ya umeme itabaki hata baada ya chanzo cha nguvu imekuwa disconnected, kama capacitor ina athari ya malipo. Wakati electrodes ya capacitor kushtakiwa ni shorted, kutakuwa na mtiririko wa muda wa sasa, na malipo kuhifadhiwa itakuwa neutralized na kutoweka. Hivyo, capacitor ni discharged.
