Indorerwamo igabanya imirasire yashyizwe muri gare. Igizwe nindorerwamo idasanzwe hamwe na diode ebyiri zifoto hamwe na elegitoroniki. Umugenzuzi wa elegitoronike yakiriye urumuri rwimbere hamwe ninyuma yinyuma yoherejwe na Diode ya Photose. Niba urumuri rumurikira rumurikira mu ndorerwamo yimbere, niba urumuri rwinyuma runini kuruta urumuri rwimbere, umugenzuzi wa elegitoroniki azasohora voltage kumurongo uyobora urwego ruyobora. Voltage kumurongo uyobora uhindura ibara ryindorerwamo ya electroche. Hejuru voltage, wijimye ibara ryikipe ya elegicechemical. Muri iki gihe, nubwo abafashe kumurika ku ndorerwamo zitandukanye, anti-urumuri mu ndorerwamo yihindagurika ryerekanaga amaso yumushoferi azerekana urumuri rwijimye, ntabwo rutangaje
