The anode is which of the following?

• A. Positive electrode
• B. Negative electrode
• C. Neutral electrode
• D. Ground electrode

Answer: (A)

In this context, the anode is the positively charged electrode. In many clinical electrical devices and therapies, the electrode connected to the positive terminal of the power source is designated as the anode, while the other electrode is the cathode (negative). This polarity matters because it guides how ions and current move at the treatment site and influences the tissue response. Ground or neutral electrodes are separate concepts and don’t define the anode in this setup.
