Etymology

The word 'anode' originates from the Greek term 'anodos', which means 'way up' or 'ascent'. It was first introduced in the context of electrochemistry in the mid-19th century, particularly by the chemist Michael Faraday. The term was chosen to reflect the direction of conventional current flow, which is defined as moving from the anode to the cathode. Throughout the years, the concept of an anode has evolved and expanded, with its application in various technologies such as batteries, diodes, and electroplating, making it a foundational element in electrical engineering.
