What is electrode?

• Electrode, electric conductor, usually metal, operated as either of the two terminals of an electrically operating medium; it conducts current into and out of the medium, which may be an electrolytic resolution as in a storage battery, or a solid, gas, or vacuum.

• The main use of electrodes is to generate electrical current and pass it through non-metal objects to essentially alter them in several ways. Electrodes are also used to calculate conductivity.

• The electrode is the location where electron transfer happens. An electrode is classified as either a cathode or an anode counting on the type of chemical response that happens. If an oxidation reaction happens at an electrode.
