What do we call the conductive element used to make contact with a non-metallic part in an electrical system?

The term used to describe the conductive element that makes contact with a non-metallic part in an electrical system is "electrode." Electrodes are crucial components in various electrical applications, as they facilitate the transfer of electrical energy by creating a connection between conductive and non-conductive materials. This enables current to flow through the circuit, impacting how treatments are performed in a beauty therapy context, particularly in electrical modalities like electrotherapy.

When electrodes contact non-metallic parts—such as skin during an electrotherapy treatment—they allow for effective conduction of electrical currents through the body, aiding in various therapeutic procedures. Understanding the function of electrodes enhances knowledge of how electrical applications can be harnessed safely and effectively in beauty therapy practices.
