Which electrode is traditionally referred to when discussing the negative pole?

The correct choice is the cathode, which is traditionally referred to as the negative pole in electrical terminology. In electrolysis and various electrochemical processes, the cathode is the electrode where reduction occurs, meaning it gains electrons from an external circuit. As a result, it is associated with the negative charge in a system because it attracts positively charged ions (cations) and provides electrons to them.

The anode, in contrast, is the positive pole where oxidation occurs, losing electrons to the external circuit. Understanding the difference between these two types of electrodes is crucial in practices such as waxing, where equipment might rely on electrolysis principles for hair removal. Additionally, electrodes and current conductors are terms that describe broader aspects of electrical systems but do not specifically define the role of either the anode or cathode as the negative or positive poles. Thus, the cathode being referenced as the negative pole aligns with standard terminology in both electrical science and cosmetology practices involving electrical modalities.
