The combined changes between electrodermal resistance and electrodermal potential make up electrodermal activity. Galvanic skin resistance (GSR) is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them. The electrodes are normally placed about an inch ...
Skin effect reduces the effective cross-section of the conductor and thus increases its effective resistance. At 60 Hz in copper, skin depth is about 8.5 mm. At high frequencies, skin depth becomes much smaller. Increased AC resistance caused by skin effect can be mitigated by using a specialized multistrand wire called litz wire. Because the ...

The galvanic series (or electropotential series) determines the nobility of metals and semi-metals. When two metals are submerged in an electrolyte, while also electrically connected by some external conductor, the less noble (base) will experience galvanic corrosion. The rate of corrosion is determined by the electrolyte, the difference in ...
EDA used to be known as the galvanic skin response, which is the combination of the changes in the galvanic skin resistance and galvanic skin potential. The polygraph measures the EDA, respiration and heart rate. [6]
Galvani's name also survives in everyday language as the verb 'galvanize' as well as in more specialized terms: Galvani potential, galvanic anode, galvanic bath, galvanic cell, galvanic corrosion, galvanic couple, galvanic current, galvanic isolation, galvanic series, galvanic skin response, galvanism, galvanization, hot-dip galvanization ...
A galvanic cell's anode is less negative, supplying less energy than thermodynamically possible. A galvanic cell's cathode is less positive, supplying less energy than thermodynamically possible. The overpotential increases with growing current density (or rate), as described by the Tafel equation. An electrochemical reaction is a combination ...
In electrochemistry, a thermogalvanic cell is a kind of galvanic cell in which heat is employed to provide electrical power directly. [1] [2] These cells are electrochemical cells in which the two electrodes are deliberately maintained at different temperatures. This temperature difference generates a potential difference between the electrodes.
