Which electrode is the positive electrode in electrotherapy?

Which electrode is the positive electrode in electrotherapy?

• A. Cathode
• B. Ground
• C. Anode
• D. Nonconductor

Answer: (C)

In electrotherapy using direct current, the positive electrode is the anode. The electrode connected to the positive terminal of the power source becomes the positive electrode, and the anode is the site of oxidation while it attracts anions (negative ions) from the tissues. The opposite electrode is the cathode, which is negative. Ground and nonconductive materials aren’t used as active electrodes in this context, since they don’t function as electrodes carrying current.
