What color is typically associated with the cathode?

The cathode is typically associated with the color red. This is a standard convention in electrical and electronic applications. The cathode serves as the electrode where reduction reactions occur, which is when electrons are gained. In many devices, especially batteries, the red color is used to indicate the positive terminal, which is essential for ensuring proper connections and safety when handling electrical equipment.

The colors associated with electrodes, such as black for the anode and red for the cathode, help differentiate their functions and roles in circuitry and electric systems. This clarity helps technicians and users manage and troubleshoot electrical systems correctly.
