Which electrode is held by a client to create a circuit?

• A. Anode Electrode
• B. Cathode Electrode
• C. Grounding Bar Electrode
• D. Sparking Electrode

Answer: (C)

The key idea is safety and completing the electrical loop. In facial treatment devices that use multiple electrodes, two electrodes (the anode and the cathode) deliver current into the body. To make the circuit work, there must be a return path for that current. The grounding bar electrode serves as the return path and is the one the client holds to complete the circuit safely. Holding the grounding bar ensures the current travels from the device through the active electrode into the body and back through the grounding electrode to the device’s safety ground, minimizing stray current and reducing risk. The sparking electrode would not be used for standard treatments because it’s designed to create arcs, which is unsafe for cosmetic procedures.
