What is another word for electrolytic capacitor?
Pronunciation: [ɛlˌɛktɹəlˈɪtɪk kəpˈasɪtə] (IPA) 
An electrolytic capacitor is a widely used electronic component designed to store electrical energy. However, it is also known by several other names. One of the synonyms for an electrolytic capacitor is "electrochemical capacitor" which refers to the fact that it stores energy via an electrochemical reaction. Another synonym is "polarized capacitor" because it can only be operated with a positive voltage on the anode and a negative voltage on the cathode. Finally, it is sometimes referred to as an "aluminum capacitor" or "tantalum capacitor" which are two common materials used in their construction. Regardless of the name, electrolytic capacitors remain essential components in a wide range of electronic devices.
