What is the designation of the negative electrode?

The designation of the negative electrode is referred to as the cathode. In the context of electrical and electrochemical systems, the cathode is the electrode where reduction occurs, meaning that it gains electrons. This is fundamental in understanding how circuits work, especially in practices involving electrical stimulation or the use of galvanic currents in skin care or other beauty treatments.

The significance of the cathode being the negative electrode lies in its role in the flow of electricity: electrons are emitted from the negative terminal (the cathode) and move towards the positive terminal (anode) through the conductive medium. This movement of electrons is essential for maintaining the flow of current in various applications, including those in the beauty industry and other electrical devices.

Understanding this relationship is crucial for effectively applying techniques involving electricity and for using equipment safely and efficiently in professional settings.
