An applicator that directs electric current from a machine to the client's skin is a(n) _____.

• A. Electrode
• B. Probe
• C. Pad
• D. Anode

Answer: (A)

In electrotherapy, the component that carries the current from the machine to the skin is called an electrode. It’s the conductor that makes contact with the skin and completes the electrical circuit, delivering the current to the treatment area. Different shapes or forms, like pads or probes, are simply variations of electrodes designed for different contact areas or treatments. An anode refers to a specific polarity of an electrode (the positive one), so it’s a type of electrode rather than the general term for the applicator. This is why the best answer is electrode.
