Galvanic
Galvanic refers to the direct current of electricity, particularly when it is produced by chemical reactions. The term is often used in the context of galvanic cells, galvanic corrosion, and galvanic skin responses.
Galvanic Cells[edit | edit source]
A Galvanic cell is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell. It generally consists of two different metals connected by a salt bridge or a porous disk.
Galvanic Corrosion[edit | edit source]
Galvanic corrosion is an electrochemical process in which one metal corrodes preferentially when it is in electrical contact with another, in the presence of an electrolyte. This type of corrosion is often seen in structures built with different metals, and can lead to structural failure.
Galvanic Skin Response[edit | edit source]
The galvanic skin response (GSR) is a method of measuring the electrical conductance of the skin, which varies with its moisture level. This is of interest in the field of psychophysiology, as the moisture level of the skin changes in response to stress or arousal.
