In metals is current conduction caused by electron cloud, which are freely moving electrons of the highest valence sphere, whereas in electrolytes is electric current conducted thanks to anions and cations, moving in solutions.
Katika vyuma na sasa Husababishwa na conduction elektroni wingu, ambayo ni uhuru kusonga elektroni ya tufe juu Valence, Ambapo katika elektroliti na shukrani umeme sasa umefanywa kwa anions na cations, kuhamia katika ufumbuzi.
