No, protons do not originate from an anode. Protons are subatomic particles that are found within the nucleus of an atom. The nucleus is composed of protons and neutrons, and it carries a positive charge due to the presence of protons.
An anode, on the other hand, is an electrode in an electrical circuit that carries a positive charge. In certain electrical devices, such as in electrolysis or certain types of discharge tubes, positive ions can be attracted to the cathode (negative electrode) and negative ions or electrons can be attracted to the anode. However, these ions are not protons but rather charged atoms or molecules.
In summary, protons are not generated or originate from an anode. They are fundamental particles that are inherent to the structure of atoms and are found within the nucleus of an atom.
