In an electrolysis setup and general circuit terminology, the positive pole is commonly referred to as the anode. The anode is the electrode where oxidation occurs, which means it is the site where electrons are drawn away from the chemical species being oxidized. In this context, the positive charge at the anode attracts positively charged ions from the electrolyte, facilitating the flow of current.

Understanding the distinction between the various components of a circuit is key. While electrodes are important components that facilitate the flow of electrons, the term "anode" specifically denotes the positive electrode in this scenario. The cathode, on the other hand, is the negative pole where reduction occurs—this term is often confused with anode due to their roles in the electrochemical processes. Ground refers to a common return path for electric current but does not specify a positive pole. Therefore, the precise terminology is critical when discussing circuit roles, and the designation of the anode as the positive electrode is widely accepted in both electrochemical and electrical contexts.
