Question: 1 / 400

An anode is usually marked in what color?

Blue

Green

Red

An anode is typically marked in red to help differentiate it from the cathode, which is identified by a different color. This color-coding is essential in electrotherapy and esthetic practices, where proper identification of equipment components is crucial for safety and efficacy.

Knowing the color of an anode is important because it allows an esthetician to correctly connect equipment and apply treatments like galvanic or microcurrent therapies, ensuring that the electrical currents flow accurately through the treatment area. The emphasis on using the correct color aids in preventing mistakes that could lead to ineffective treatments or client discomfort. Understanding this standard allows estheticians to work confidently and proficiently with their tools.
