An electrode is a piece of wire or rod (of a metal or alloy), with or without flux covering, which carries current for welding. At one end it is gripped in a holder and an arc is set up at the other end. Electrode, electric conductor, usually metal, used as either of the two terminals of an electrically conducting medium; it conducts current into and out of the medium, which may be an electrolytic solution as in a storage battery, or a solid, gas, or vacuum. What are Electrodes? Electrodes are defined as solid electric conductors that let electric current enter or leave an electrolytic cell, converting ionic potentials to electronic potentials. Different types of electrodes are used for biological measurements depending on where the bioelectric signals are taken from. These electrodes can acquire signals like… Such as Metal–metal soluble salt electrode, Gas–ion electrode, Redox electrode, Metal–metal insoluble salt electrode, Calomel Electrode, and Amalgam electrode.
