What color is typically used to indicate that an electrode is a cathode?

• A. Red
• B. Black
• C. Blue
• D. Green

Answer: (B)

In the context of electrical devices and esthetician practices, electrodes are classified by their roles in electrical currents. The cathode is the negative terminal in most electrotherapy applications. The color that is commonly used to indicate a cathode electrode is black. This standard is widely adopted in various industries to enhance safety and clarity when using electrical equipment. Having a consistent color code helps practitioners quickly and accurately identify the type of electrode they are working with, thereby reducing the chances of mistakes in treatment protocols. For example, when using galvanic or other forms of electrotherapy in esthetics, it is crucial to correctly identify which electrode is which, as using them incorrectly could lead to undesired effects or harm to the client. Black is recognized by many professionals as denoting the negative pole due to its historical and practical usage in electrical applications.
