An Electrode is an electrical conductor that makes contact with the non-metallic part of a circuit. Anode and Cathode are two electrodes used in an electrochemical cell. The anode is where electrons leave the cell to generate oxidation and Cathode is where electron enters the cell and reduction occurs. The direction of the current determines whether an electrode will become an anode or a cathode. A bipolar electrode is the one that acts like the anode of one cell and cathode of another cell.

Types of Electrodes: -
Welding electrodes: - These type of electrodes are used to conduct electricity through a work piece to fuse pieces together. The electrode is consumable or non-consumable depending on the process of welding. In case of shielded arc welding the electrode is consumed and in case of gas tungsten arc welding the electrode is non-consumable.
Alternating current electrodes: - for alternating current circuits, the electrodes act as a connection from the circuit to the object. In Alternating circuits the electrodes are not named because the flow of electrons changes periodically.
Uses of Electrodes: -
Electrodes have many different purposes such as: -
