Question: 1 / 400

What color is the anode in electrical terms?

Red

Black

In electrical terms, the anode is typically associated with the color red. This color is used to identify the positive terminal in many electrical configurations, including batteries and certain types of electronic equipment. The role of the anode is critically important; it is the electrode through which the conventional current flows into a polarized electrical device.

While black is often used to denote the negative terminal, it does not represent the anode. Other colors, such as green and blue, may signify different purposes in electrical systems but are not standard representations for the anode itself. Understanding these color codes is essential for anyone working with electrical devices to ensure proper connections are made and to avoid potential hazards.
