Electrode

An electrode is a conductor through which electricity enters or exits a device or material. It is typically made of metal or other conductive material, allowing electric current to flow into a substance like a battery, a cell, or an electrochemical system. Electrodes are essential in processes like batteries, welding, and electrolysis, where they facilitate chemical reactions or transfer of energy. They are usually designed to be compatible with the environment they are in, ensuring efficient conduction and minimal corrosion. In short, electrodes serve as the connection points between electrical sources and the substances or systems they influence.
