In electrotherapy, which electrode is the negative electrode?

Explanation:
In electrotherapy, the negative electrode is the cathode. The cathode is defined as the electrode connected to the negative terminal of the power source, and it’s the site where reduction occurs in direct current treatments. Because it carries the negative charge, the cathode attracts positive ions in the tissue, and it typically produces an alkaline (alkaline) local environment due to the production of hydroxide ions. The opposite electrode, the anode, is the positive electrode. Generic terms like “electrode” or “conductor” don’t specify polarity, so they aren’t the correct labels for the negative electrode.
