Electrode FAQs:

Q: Is an electrode an electrical conductor used to make contact with a nonmetallic part of a circuit?

A: Yes, The word was coined by William Whewell at the request of the scientist Michael Faraday from the Greek words elektron, meaning amber , and hodos, a way.

Q: Are electrodes the connections from the circuitry to the object to be acted upon by the electric current but are not designated anode or cathode because the direction of flow of the electrons changes periodically?

A: Yes, and usually many times per second.

Q: Is an electrode used to conduct current through a workpiece to fuse two pieces together?

A: Yes.

Q: Is an electrode an electrode that functions as the anode of one cell and the cathode of another cell?

A: Yes.

Q: Is an electrode usually made of an inert material?

A: Yes, such as a noble metal or graphite, to keep it from dissolving.

Q: Are electrodes used for advanced purposes in research and investigation?

A: Yes.

Q: Are electrodes used to provide current through nonmetal objects to alter them in numerous ways and to measure conductivity for numerous purposes?

A: Yes.

Q: Are electrodes electrodes that have their surfaces chemically modified to change the electrode's physical?

A: Yes, and chemical, electrochemical, optical, electrical, and transportive properties.

Q: Is an electrode either consumable?

A: Yes, and in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding.
