Electrode

The video explains the role of electrodes in different contexts: electrolysis, electric cells, and medical equipment. In electrolysis, electrodes are rods in a solution connected to a power source. In electric cells, they contact a chemical mixture. In medical devices, electrodes connect wires to the skin.
